如何衡量地質(zhì)質(zhì)上的精度?其質(zhì)質(zhì)質(zhì)?就是確很x,y,zo地質(zhì)質(zhì)由點(diǎn)質(zhì)面各質(zhì)

元素質(zhì)合而成?而其中以點(diǎn)的定位最質(zhì)重要?以下在不同情下質(zhì)一些注意事質(zhì)將況

質(zhì)行質(zhì)明。

平面質(zhì)的質(zhì)制步質(zhì)，

1、在質(zhì)合平面質(zhì)上質(zhì)取需要質(zhì)制的勘探質(zhì)?在任意一端質(zhì)取一質(zhì)始點(diǎn)。質(zhì)始

點(diǎn)個(gè)質(zhì)是勘探質(zhì)質(zhì)合質(zhì)上的一整坐質(zhì)質(zhì)的交點(diǎn)質(zhì)好。與個(gè)數(shù)

2、勘探質(zhì)平面質(zhì)中的勘探質(zhì)是一平直的質(zhì)段?所以坐質(zhì)質(zhì)在勘探質(zhì)平面質(zhì)中

的條

走向一般都是質(zhì)斜的。以質(zhì)始點(diǎn)質(zhì)基準(zhǔn)?就可以質(zhì)始質(zhì)制勘探質(zhì)平面質(zhì)了C

3、質(zhì)制質(zhì)所需的據(jù)，數(shù)

1,以質(zhì)始點(diǎn)質(zhì)起點(diǎn)位置?質(zhì)量勘探質(zhì)的質(zhì)度。

2,質(zhì)量勘探質(zhì)坐質(zhì)質(zhì)的質(zhì)角?用于判定在勘探質(zhì)平面質(zhì)上的坐質(zhì)質(zhì)位置和角度

與。3,之后根據(jù)勘探質(zhì)質(zhì)度及質(zhì)合質(zhì)合質(zhì)上的孔位位置?質(zhì)制勘探質(zhì)平面質(zhì)的外大

框小。

剖面質(zhì)的質(zhì)制步質(zhì)，

在勘探質(zhì)平面質(zhì)的基質(zhì)上?我質(zhì)可以質(zhì)制勘探質(zhì)剖面質(zhì)了。其步質(zhì)如下，1、

剖面質(zhì)就是根據(jù)勘探質(zhì)在質(zhì)合質(zhì)上的位置而切一剖面質(zhì)?然后根據(jù)勘條

探質(zhì)穿質(zhì)的地質(zhì)?在勘探質(zhì)下質(zhì)制不同的巖性質(zhì)而后最質(zhì)成質(zhì)。在質(zhì)合質(zhì)上質(zhì)

察勘條

探質(zhì)所質(zhì)質(zhì)的地形?需質(zhì)質(zhì)的據(jù)，勘探質(zhì)上各控制點(diǎn)的高程及其質(zhì)始點(diǎn)的距數(shù)

與

離、勘探質(zhì)質(zhì)質(zhì)的地質(zhì)分界位置、以及一些重要的地物的位置。2、根據(jù)以上

的據(jù)我質(zhì)可以出勘探質(zhì)上的地形質(zhì)化^^一些地質(zhì)分界質(zhì)、數(shù)畫

地物位置等。；在此提醒?如果質(zhì)需落質(zhì)孔或其他元素?質(zhì)先不急著質(zhì)剖面質(zhì)

上質(zhì)?以質(zhì)在質(zhì)制剖面質(zhì)質(zhì)?往往出質(zhì)某點(diǎn)的不注意而質(zhì)致制質(zhì)質(zhì)差?或高條會(huì)個(gè)

或低的情在質(zhì)制剖面質(zhì)質(zhì)質(zhì)常質(zhì)的質(zhì)質(zhì)?而修改起也是一件挺麻質(zhì)的事~況很

來

我想有質(zhì)質(zhì)似質(zhì)質(zhì)的同道質(zhì)也明白那質(zhì)感受。所以?我質(zhì)的口是?質(zhì)持很吧號(hào)

從

大到小的原質(zhì)?質(zhì)不質(zhì)功冒質(zhì)?不然質(zhì)生的后果質(zhì)人郁質(zhì)的。，會(huì)很

質(zhì)孔質(zhì)質(zhì)在平面質(zhì)上的落法，

在平面質(zhì)上?所質(zhì)的質(zhì)孔質(zhì)質(zhì)投影?就是把質(zhì)質(zhì)上的各點(diǎn)垂直的投影到地表平

個(gè)

面上。質(zhì)需要到質(zhì)孔的質(zhì)斜質(zhì)料了?在平面質(zhì)上?先落孔口坐質(zhì)?在平面所到

找相質(zhì)的坐質(zhì)質(zhì)?利用CAD的偏移?就可以得到孔口坐質(zhì)?其他的點(diǎn)也是一質(zhì)的做

法。一般情下~我質(zhì)取況100—200一點(diǎn)質(zhì)宜?點(diǎn)太少?質(zhì)質(zhì)質(zhì)得不質(zhì)質(zhì)個(gè)~點(diǎn)太

多?那工作量就太大?建質(zhì)看不同情而質(zhì)取定點(diǎn)距。況離

剖面質(zhì)中的質(zhì)質(zhì)質(zhì)制方法，

在剖面中?先落質(zhì)孔在剖面質(zhì)的位置在質(zhì)合地質(zhì)質(zhì)上?質(zhì)孔質(zhì)心做勘探質(zhì)從

1、

的垂質(zhì)?垂點(diǎn)質(zhì)質(zhì)孔在勘探質(zhì)上的投影點(diǎn)。質(zhì)量質(zhì)點(diǎn)質(zhì)始點(diǎn)之質(zhì)的距?利即與

離

用質(zhì)距質(zhì)孔高程可以在剖面質(zhì)上定下質(zhì)孔位置。離與

2、之后?利用質(zhì)孔質(zhì)斜;沿質(zhì)位移;注意勘探質(zhì)角度,和垂直位移,定勘探質(zhì)的

位置。利用質(zhì)質(zhì)本地質(zhì)分界據(jù)在質(zhì)斜表中質(zhì)算地質(zhì)分界的高程。質(zhì)定數(shù)體

位方法也一質(zhì)的。之后在質(zhì)制地質(zhì)質(zhì)質(zhì)~需考質(zhì)質(zhì)本所質(zhì)質(zhì)的巖性和質(zhì)角C條

參

如何用控制柄質(zhì)質(zhì)多基準(zhǔn)點(diǎn)個(gè)

不質(zhì)^青。確

另個(gè)區(qū)個(gè)一方法是?如果要質(zhì)量的域完全被質(zhì)質(zhì)象包質(zhì)?質(zhì)可以質(zhì)質(zhì)取AREA

命令的

Object質(zhì)質(zhì)。

如果質(zhì)域不是質(zhì)質(zhì)象?那質(zhì)最好用區(qū)個(gè)PEDIT命令質(zhì)成一質(zhì)象。將它個(gè)當(dāng)指向

質(zhì)中的質(zhì)質(zhì)質(zhì)~

AutoCAD會(huì)它并將它提示用質(zhì)不是多質(zhì)質(zhì)?質(zhì)質(zhì)是否質(zhì)質(zhì)質(zhì)多質(zhì)質(zhì)。回答Y~

然后用Join子

命令其他質(zhì)象質(zhì)將它與來個(gè)接起?質(zhì)建質(zhì)質(zhì)象。完成后?就可以使用AREA命

令的

Object質(zhì)質(zhì)0

當(dāng)區(qū)確質(zhì)域被質(zhì)質(zhì)后?可以使用EXPLODE命令質(zhì)些質(zhì)象將拆來狀散回原的質(zhì)。

另個(gè)一方法是使用REGION命令質(zhì)取各質(zhì)象?質(zhì)質(zhì)成一質(zhì)象。其步質(zhì)質(zhì)個(gè)它將

會(huì)個(gè)它與

多質(zhì)質(zhì)質(zhì)接方法相同。最后也可以用EXPLODE命令質(zhì)域?qū)^(qū)拆來狀散回原質(zhì)。

質(zhì)入,AREA〈回質(zhì)》;或者從ObjectProperties工具質(zhì)中質(zhì)質(zhì)。，

響質(zhì)，/Objcct/Add/Subtract:

質(zhì)入,0＜回質(zhì)）

響質(zhì)，Selectcircleorpolyline:

如何質(zhì)文本加下質(zhì)或作質(zhì)質(zhì)劃

在要加下質(zhì)或作質(zhì)質(zhì)的文本的劃插號(hào)號(hào)將前后入以下符?質(zhì)些符質(zhì)嵌在文本行

中。，，u下質(zhì)質(zhì)或質(zhì)劃

,,0上質(zhì)質(zhì)或質(zhì)劃

例如，Thiswordisunderlinedo

質(zhì)按以下方式質(zhì)入，

This,,uword,,uisunderline。

如何完全改質(zhì)文本字體

所有的文本字都是體通近STYLE控制?因此?如果用質(zhì)希望改質(zhì)文本字就體必

質(zhì)改質(zhì)文本質(zhì)式~質(zhì)可以通質(zhì)CHANGEPoint命令完成。如果質(zhì)取的質(zhì)象是文本~

其中一個(gè)質(zhì)質(zhì)就是stylco

但是?如果要用CHANGE命令修改大量的文本?就比質(zhì)困質(zhì)?因質(zhì)常常質(zhì)中其

他質(zhì)型會(huì)的質(zhì)象?而造成質(zhì)性的后果。如果改質(zhì)質(zhì)式的定質(zhì)?質(zhì)中同一質(zhì)式的所有

文本的字都災(zāi)體

會(huì)當(dāng)改質(zhì)“因此只有需要改質(zhì)所有文本質(zhì)才能使用此方法。

的486微機(jī)?可以質(zhì)快地質(zhì)制地質(zhì)質(zhì)。下面分質(zhì)介質(zhì)質(zhì)些方法。以供同行考。參

1.多建質(zhì)多使用質(zhì)地質(zhì)質(zhì)中常用的將學(xué)號(hào)固定不質(zhì)的成分如質(zhì)例、質(zhì)任質(zhì)、

質(zhì)尺、水化質(zhì)型符、質(zhì)孔、探井、不同質(zhì)型的質(zhì)床和質(zhì)點(diǎn)、地質(zhì)年代符等建成質(zhì)?

質(zhì)存入某號(hào)并將它個(gè)子目質(zhì)中~構(gòu)成零件質(zhì)。在質(zhì)制地質(zhì)質(zhì)質(zhì)~通質(zhì)質(zhì)操作~直接

使用質(zhì)些成分。質(zhì)質(zhì)作^一方面質(zhì)化了操作?大大少了重質(zhì)質(zhì)質(zhì)的減數(shù)另號(hào)次?加

快了質(zhì)質(zhì)速度?一方面質(zhì)一了符?提高了質(zhì)形的美質(zhì)程度?再者?如果某質(zhì)符出質(zhì)

?只需改質(zhì)號(hào)零件質(zhì)中質(zhì)質(zhì)的零件~不必在質(zhì)形中修改每個(gè)號(hào)符~提高了質(zhì)質(zhì)

修改速度。

2.質(zhì)質(zhì)形質(zhì)行分質(zhì)每一質(zhì)上放置某一質(zhì)地質(zhì)形?如等高質(zhì)、等體構(gòu)深質(zhì)、地

物、地質(zhì)、造、巖性、水系、化質(zhì)型、勘探工程等。如質(zhì)學(xué)1、質(zhì)2、質(zhì)3和質(zhì)

4。其中質(zhì)1是要質(zhì)制的水文地質(zhì)質(zhì)?先其按質(zhì)面將內(nèi)劃區(qū)容不同?分質(zhì)地物等水

位質(zhì)質(zhì)質(zhì)?1等高質(zhì)質(zhì)質(zhì)，區(qū)2等高質(zhì)質(zhì)質(zhì)?分質(zhì)如質(zhì)2?質(zhì)3?質(zhì)4。質(zhì)將2、質(zhì)

3、質(zhì)4內(nèi)容分質(zhì)質(zhì)制在dw質(zhì)質(zhì)、dxl質(zhì)質(zhì)和dx2質(zhì)質(zhì)上?質(zhì)各個(gè)并體質(zhì)質(zhì)分質(zhì)質(zhì)

質(zhì)~使質(zhì)些質(zhì)質(zhì)上形的質(zhì)型、質(zhì)色和所在質(zhì)質(zhì)一致~質(zhì)質(zhì)作一方面~通質(zhì)改質(zhì)質(zhì)質(zhì)

的質(zhì)型、質(zhì)色就可以改質(zhì)質(zhì)質(zhì)上的所有地質(zhì)的質(zhì)型和質(zhì)色?體另加快質(zhì)質(zhì)修改速

度。一方面?通質(zhì)質(zhì)質(zhì)不需要質(zhì)質(zhì)的形所在的質(zhì)質(zhì)質(zhì)質(zhì)起?在重新生成質(zhì)?質(zhì)些形

不再重新生成?將體來體將

提高重新生成速度?同質(zhì)?由于質(zhì)形質(zhì)質(zhì)質(zhì)形質(zhì)質(zhì)質(zhì)?利于質(zhì)質(zhì)。重新生成是

影質(zhì)質(zhì)區(qū)響速度的主要因素?質(zhì)了質(zhì)一步加快質(zhì)質(zhì)速度?質(zhì)可以通質(zhì)質(zhì)置AutoCAD

自質(zhì)重新生成質(zhì)參數(shù)0?避免不必要的重新生成?以質(zhì)一步提高質(zhì)質(zhì)速度。

3.建立地質(zhì)質(zhì)用質(zhì)案質(zhì)?使用質(zhì)案充填來填填填完成大面質(zhì)色質(zhì)充和巖性花質(zhì)

的充。質(zhì)案充的速度主要取于定質(zhì)界的決確速度。AutoCAD提供了質(zhì)定質(zhì)兩確填充

質(zhì)界的方法，質(zhì)質(zhì)目質(zhì)方式?質(zhì)方式不用搜索質(zhì)界?但需要質(zhì)先構(gòu)填構(gòu)筑質(zhì)界。點(diǎn)

充方式?質(zhì)方式不需要質(zhì)先筑質(zhì)界但需要在可質(zhì)區(qū)內(nèi)填填搜索質(zhì)界。地質(zhì)質(zhì)形中充

質(zhì)界多質(zhì)不質(zhì)質(zhì)質(zhì)界?一般用點(diǎn)充方式來確當(dāng)區(qū)很定質(zhì)界。質(zhì)幅質(zhì)大?質(zhì)界不質(zhì)合

?因局部搜索域大大質(zhì)大?搜索速度慢?有質(zhì)搜索一域質(zhì)界大質(zhì)需要個(gè)區(qū)20-60分

質(zhì)。按質(zhì)質(zhì)的質(zhì)界搜索速度質(zhì)質(zhì)地質(zhì)質(zhì)形?幾沒乎什質(zhì)質(zhì)用價(jià)質(zhì)。由于AutoCAD

在用點(diǎn)方式搜索質(zhì)界質(zhì)?只搜索可質(zhì)域?質(zhì)區(qū)決填解點(diǎn)充方式搜索質(zhì)界速度慢的質(zhì)

質(zhì)?可以引用質(zhì)助質(zhì)?用質(zhì)些質(zhì)助質(zhì)首先將填區(qū)劃個(gè)充分質(zhì)若干相質(zhì)質(zhì)質(zhì)質(zhì)的接近

正方形的子區(qū)個(gè)區(qū)填個(gè)區(qū)填將盡?然后質(zhì)各子分質(zhì)質(zhì)行充。質(zhì)每子充質(zhì)?先其可能

放大?然后質(zhì)質(zhì)用點(diǎn)方式定質(zhì)界?質(zhì)質(zhì)可以區(qū)確加快搜索質(zhì)界速度。

4.不質(zhì)質(zhì)質(zhì)滑質(zhì)界的質(zhì)理先不質(zhì)質(zhì)質(zhì)將離滑曲質(zhì)散成多質(zhì)質(zhì)?多質(zhì)質(zhì)的質(zhì)點(diǎn)

質(zhì)曲質(zhì)的控制點(diǎn)」然后質(zhì)多質(zhì)質(zhì)質(zhì)行質(zhì)質(zhì)°質(zhì)質(zhì)質(zhì)先質(zhì)行質(zhì)接~截除、延伸等操

作?最后質(zhì)多質(zhì)質(zhì)質(zhì)行質(zhì)滑操作。質(zhì)滑質(zhì)可以采用FIT方式和SPLINE方式。FIT

方式質(zhì)生的曲質(zhì)"定通質(zhì)控制點(diǎn)~油質(zhì)有質(zhì)弧構(gòu)數(shù)成~據(jù)量小。SPLINE方式~

質(zhì)方式質(zhì)生的質(zhì)滑曲質(zhì)質(zhì)平滑?但曲質(zhì)不一定通質(zhì)控制

點(diǎn)?質(zhì)滑后的曲質(zhì)和原曲質(zhì)存在一定的偏移?據(jù)量大。在一般地形質(zhì)中?數(shù)

SPLINE方式和FIT方式相比?前者質(zhì)生的據(jù)量質(zhì)是后數(shù)者的2倍?采用FIT方式

可以少質(zhì)減形的據(jù)量?有效提高質(zhì)質(zhì)數(shù)速度。因此一般質(zhì)采用FIT方式質(zhì)滑?在要

求曲質(zhì)特質(zhì)光滑?而又不需要曲質(zhì)一定通質(zhì)控制點(diǎn)?才使用SPLINE方式質(zhì)滑曲

質(zhì)。

5.采用外部參將內(nèi)個(gè)考地質(zhì)質(zhì)上的容按性質(zhì)不同?分質(zhì)質(zhì)制在不同質(zhì)形上?

每質(zhì)形上都質(zhì)定一質(zhì)形個(gè)校準(zhǔn)點(diǎn)。先質(zhì)每一質(zhì)形質(zhì)行質(zhì)質(zhì)?然后在質(zhì)合質(zhì)中引用質(zhì)

些質(zhì)一質(zhì)形。由于質(zhì)幅質(zhì)的數(shù)與數(shù)減據(jù)量相質(zhì)整幅質(zhì)的據(jù)量成倍地被少?所以可以

加快質(zhì)幅質(zhì)形的質(zhì)質(zhì)速度。如質(zhì)5、質(zhì)6、質(zhì)7和質(zhì)8o質(zhì)5是要質(zhì)制的水文地質(zhì)
