重慶市軌道交通環線冉家壩車站巖土工程詳細勘察報告①地下水對對混凝土結構有微腐蝕性，對混凝土結構中的鋼筋有微腐蝕性。②在樁基過程中，地下水可能導致樁孔垮孔、縮徑，使得土層中成樁難度加大。因此建議施工時應所好充分的抽排準備，并做好相應護壁措施保障樁孔質量，必要時可采用鋼護筒或混凝土護壁等措施，在緊鄰水田、魚塘等地表水體區域存在穩定水位的樁孔內可采用水下混凝土澆筑保證成樁質量。=3\*GB3③管廊基坑施工時應減輕對地基巖體的擾動，對基坑壁、基底滲水嚴重的呈線狀、股狀的滲水點可作注漿止水，清除因施工影響而松動的巖塊及浮渣后，及時對底板進行原槽澆筑、對邊墻與基坑壁之間采用混凝土搗實充填，確保混凝土與巖體之間接觸良好，并做好地表防、排水措施，經上述處理后，可不考慮水浮力；如果未對基坑進行處理或四周回填不密實以及基礎砼與巖石接觸不良時，則需考慮抗浮，宜以地面高程為托浮設計水位起算。5.8路基均勻性評價5.9地基及基礎根據設計方案，按設計方案平場后，場地覆蓋層厚度差異大，出露人工填土、粉質粘土、強風化、中風化砂巖、砂質泥巖。高架橋橋墩、抗滑樁采用樁基礎，以中風化基巖作為基礎持力層；當基巖埋深較深時，建議橋臺采用樁基礎，以中風化基巖作為基礎持力層，當基巖埋深較淺時，建議橋臺采用淺基礎，以中風化基巖作為基礎持力層；路基段擋墻根據設計標高及基巖埋深情況以基巖、壓實填土或換填地基作為持力層。路基根據開挖揭露情況可直接以下伏基巖或壓實填土作為持力層。5.10路基干濕類型評價根據《市政工程地質勘察規范》DBJ50-174-2014第4.3章節路基路基干濕類型應根據不利季節路床頂面以下80cm深度內路基土的濕度狀況確定。勘察場地內現狀路基和擬建路基下伏巖土主要為人工填土，為中~強透水層，且現狀路基和擬建路基標高均高于沿線溪溝的最高洪水位標高，場地內路基干濕類型可按干燥或中濕狀態考慮。5.11成樁可行性及施工條件分析5.11.1成樁可能性根據對勘察資料的分析整理，該場地平場后地層由上而下依次為：第四系全新統人工填土、殘坡積層、基巖為侏羅系中統沙溪廟組(J2s)沉積巖層(砂巖、砂質泥巖)。根據結合重慶地區施工經驗，本地區一般采用機械成孔和人工挖孔，該兩類成樁工藝在該場地巖、土中施工成樁均可行。場地人工填土層主要呈松散狀，但其顆粒組成不均勻，在樁孔成孔過程中受擾動后易垮塌；場地粉質粘土層厚度分布不均，在樁孔成孔過程中容易出現縮徑等影響成樁質量；同時由于土層較厚區域存在不穩定的地下水，會對成樁造成一定的困難。因此土層中成樁條件差，施工困難較大。場地基巖物理力學性質穩定，成樁條件好。場地人工填土中碎塊石的母巖為軟硬差異明顯的砂巖與砂質泥巖，采用機械成孔時，土中砂巖塊石隨鉆頭轉動導致擾動區域增大進而影響孔壁穩定，同時影響孔底沉渣厚度。施工時應充分考慮以上情況，配以合理的輔助措施確保施工安全和成樁質量。5.11.2施工條件及注意事項人工挖孔受地形條件及樁形限制較小，施工時應對有毒有害氣體作好探查和預防工作，切實做好排風、排水措施，防止井口墜物，防止漏電，作好井壁支護等安全措施，防止安全事故的發生。根據渝建發（2019）25號文，人工挖孔樁屬于限制使用的落后工藝，不建議使用。當樁孔采用機械成孔時，在地下水(或掘進冷卻液)潤濕和切割刀具擾動的共同作用下，易產生“糊鉆”粘結現象或堵塞渣口等情況，影響掘進效率，應考慮適當的掘進輔助措施。場地砂巖自然抗壓強度高，石英含量較高，對刀具的磨損較大，因此，在掘進設備選型時，應對此有充分考慮。根據本場地的實際情況，建議設備的掘進參數中巖石抗壓強度宜確定為砂巖自然抗壓強度的最大值的2倍。場地內大部分橋墩位處下伏填土厚度較大，塊石含量較大，在懸挖機推進過程中，接觸關系為點對面接觸，經過懸挖機帶動填土內塊石，易形成較大范圍內的塌孔現象，施工過程中應做好相應的預案措施。通過縱斷面圖顯示，回填土厚度較大的墩位區域鄰近隱伏巖坎，建議施工時先施工陡坎外側嵌巖較淺的樁、避免形成高低樁,并結合實際情況合理調整樁基礎埋置深度。擬建場地地下水較發育，地下水水量及水位受降雨影響顯著，將對覆蓋層厚度較大的圍護樁成樁孔壁垮塌加劇，樁基施工受降水影響大。建議在旱季進行施工，在施工時應配備必要的排水設備并做好相應的預案。綜上，機械成孔對垮孔、縮徑、垂直度及孔底沉渣厚度等控制難度較大，施工質量難以直觀判別；優點為安全、高效。施工時應充分考慮以上情況，配以合理的輔助措施確保安全和成樁質量。采用人工挖孔時應嚴格按照《渝建發》(2012)117號文《關于進一步加強樁基礎施工安全管理的通知》進行施工，施工前應根據《關于進一步加強人工灌注樁管理的通知》(2012)162號文的規定，上報有關部門，組織相關人員、專家進行人工挖孔樁可行性的專項論證。根據渝建發（2019）25號文，人工挖孔樁屬于限制使用的落后工藝，不建議使用。5.12對環境的影響評價擬建工程施工對環境的影響主要體現在對道路的影響以及對自然環境的影響兩個方面，現分述如下:對道路的影響評價擬建場地內存在多條市政及鄉村道路，立交施工開挖將封閉該段道路，施工前應施工時加強邊坡的支護工作，并做好地面的監測工作擬建場地主線里程K0+240~K0+260段內存在一條市政道路，擬建擬建道路將采用上跨橋形式跨越該市政道路，基本上不會進行挖填方，按設計方案施工對已有市政道路工程影響較小。擬建場地主線里程K0+940~K1+060段為長石街，施工時將截斷該道路，施工前應施工時加強邊坡的支護工作，并做好地面的監測工作施工開挖對自然環境的影響評價擬建工程鄰近居民小區、高速路、市政道路、溪流，施工時應嚴格按照國家及重慶市有關環保及衛生方面的規定，禁止廢碴、廢水等隨意排放污染鄰近水庫，控制施工噪音等，通過合理的施工組織安排，盡量減少對周圍環境及居民小區的干擾，并應注意交通安全。6地質條件可能造成的工程風險分析根據《住房城鄉建設部辦公廳關于進一步加強危險性較大的分部分項工程安全管理的通知》建辦質【2017】39號文“勘察單位應當針對工程實際，在勘察文件中說明地質條件可能造成的工程風險”的要求，本工程地質條件可能造成的工程風險主要有：（1）場地部分區域地下水較發育，地下水水量主要受大氣降水控制。在豐水期或雨季施工時，將對橋墩成樁孔壁垮塌加劇，在施工時應配備必要的抽排水設備，必要時可采取鋼護筒或混凝土護壁，確保樁壁的完整及樁身質量，避免產生缺陷樁。（2）在填方較大區域，旋挖成孔過程中，由各方面因素可能導致巖土界面層次不清，施工過程中宜分樁跳樁成孔。（3）在成樁過程中（包括邊坡上的樁孔），由于地層結構、地下水、支護強度等因素誘發井壁垮塌、井內突水與涌沙、井口上方物體墜落事故。（4）由于巖體自身的不均勻性、開挖工法、雨水浸泡、試驗誤差等因素導致地基強度不滿足設計要求。（5）邊坡垮塌，屬危險性較大的分部分項工程，為防止邊坡垮塌，建議邊坡施工過程中加強監測，當邊坡變形過大，變形速率過快，立即采取應急措施，確保安全。邊坡施工應加強觀測，及時發現異常情況，盡快向勘察和設計等單位反饋信息，調整支護措施和施工方案。按渝建發[2014]16號文的要求對該危險性較大的分部分項工程安全專項施工方案進行管理。根據渝建發[2010]166號文，該項目存在超限邊坡，建議組織專家對支護方案進行安全專項論證。7結論與建議7.1結論⑴勘察區內巖土工程條件較復雜，場地位于北碚向斜東翼，沿線原始地貌為構造剝蝕淺丘地貌。線路除主線里程K0+240～K0+540段、K0+640～K0+740段、K0+920～K1+160段、K1+300.000～K1+400.000段、K1+940.000～K1+980.000段、K2+280.000～K2+300.000段受人工改造后多為施工區、棄渣區、居民地或市政設施道路、以外，其余里程段為原始地貌，受人類活動影響較小。擬建范圍內未發現危巖崩塌、泥石流、地面塌陷等不良地質現象，巖土層種類較多，擬建范圍內區域構造作用輕微，地質構造簡單，未發現斷裂構造，巖層呈單斜產出，基巖完整性較好，地層層序正常。場地內現有溪溝兩岸岸坡穩定，無岸坡穩定性問題，擬建范圍適宜擬建工程的建設。⑵擬建工程場地覆蓋層厚度差異大，基巖為侏羅系中統沉積巖，場地內以砂巖、砂質泥巖、粉砂巖為主，中等風化基巖巖體一般較完整。⑶擬建工程場地設計地震分組為第一組，抗震設防烈度為6度，場地地震動峰值加速度0.05g。⑷擬建場地地下水及地表水按II類環境，在A類條件下，對混凝土結構有微腐蝕性，在干濕交替環境對鋼筋混凝土結構中鋼筋有微腐蝕；按II類環境，在A類條件下，場地內土對混凝土結構有微腐蝕；按地層滲透性，對混凝土結構有微腐蝕；對鋼筋混凝土結構中鋼筋有微腐蝕；對鋼結構有微腐蝕。7.2建議(1)擬建道路、擋墻、預留下穿通道、管廊、箱涵等按設計施工后位于基巖區部分可在達到設計標高后，直接以基巖作為基礎持力層；位于粉質粘土區的應對粉質粘土進行換填夯實后方可作為基礎持力層使用；位于軟土分布區的應先對軟土采取清除或拋石擠淤的方式進行處理后方可以壓實填土作為基礎持力層；位于填土區的應先對填土采取換填夯實或壓實處理后方可作為基礎持力層；換填夯實、壓實填土部分應分層碾壓達到設計和規范要求。擬建高架橋的橋臺及橋墩、擬建樁板擋墻應采用中等風化基巖為基礎持力層(2)(3)(4)沿線岸坡穩定，在洪水位期間工況下，岸坡整體處于穩定狀態，建議對道路穿越的溪溝進行渠化改造。管廊基坑施工時應減輕對地基巖體的擾動，對基坑壁、基底滲水嚴重的呈線狀、股狀的滲水點可作注漿止水，清除因施工影響而松動的巖塊及浮渣后，及時對底板進行原槽澆筑、對邊墻與基坑壁之間采用混凝土搗實充填，確保混凝土與巖體之間接觸良好，并做好地表防、排水措施，經上述處理后，可不考慮水浮力；如果未對基坑進行處理或四周回填不密實以及基礎砼與巖石接觸不良時，則需考慮抗浮，宜以地面高程為托浮設計水位起算。管廊穿越現有溪溝時，應做好溪溝引流改道工作，防止地表水進入開挖基坑。管廊的開挖過程中應做好截排水措施防止地表水進入基坑，并做好準備好抽排設備，施工中如遇局部基巖滲水，應及時抽排，避免雨季施工。擬建道路現有溪溝位置，其兩側沿線地下水較發育，地下水水量及水位受河水漲落的影響顯著，在樁基過程中，地下水可能導致樁孔垮孔、縮徑，使得土層中成樁難度加大；建議施工時應所好充分的抽排準備，并做好相應護壁措施保障樁孔質量，必要時可采用鋼護筒或混凝土護壁等措施，局部存在地下水的樁位可采用水下混凝土澆筑保證成樁質量。施工區位于現有市政道路范圍內的，建議施工前應組織好道路交通并對施工區進行有效隔離，并應注意出渣車輛及人員交通安全。附表4.1-1砂質泥巖室內試驗成果統計表巖石名稱巖樣編號物理指標力學性指標顆粒
