25、為一層地下室及二層地下室交界部位，現(xiàn)狀已開(kāi)挖至一層地下室基坑底，二層地下室開(kāi)挖時(shí)采用大放坡形式，不作基坑支護(hù)。三、地質(zhì)概況三、地質(zhì)概況1、地質(zhì)情況：擬建場(chǎng)地地貌單元屬于較為平緩的低山殘丘和沖積盆地。自上而下土層大致如下：①素填土，灰色，濕，松散，密實(shí)度差，平均層厚2.94m；②粘土，灰紅、灰黑色，飽和、可塑狀，平均層厚4.3m，承載力特征值100KPa；③砂質(zhì)粘土，由花崗巖風(fēng)化殘積而成，褐色，堅(jiān)硬狀，平均層厚5.59m，承載力特征值23

26、0KPa；④1全風(fēng)化花崗巖，灰白色，遇水易軟化，平均層厚10.86m，承載力特征值350KPa；④2強(qiáng)風(fēng)化花崗巖，灰色，極軟巖，平均層厚5.96m，承載力特征值550KPa；④3中風(fēng)化花崗巖，褐色，質(zhì)地較堅(jiān)硬，頂層深度17.1~36.5m，承載力特征值2000KPa；2、地下水位情況：場(chǎng)區(qū)地下水類(lèi)型主要為第四系松散土類(lèi)孔隙水及基巖裂隙水，屬潛水，地下水量不豐富，主要以大氣降水為主。四、周邊環(huán)境及管線概況四、周邊環(huán)境及管線概況1、本基坑工

27、程所處地段的周邊環(huán)境：本工程地下室基坑南側(cè)及西南側(cè)外為一期項(xiàng)目部臨時(shí)建筑，臨時(shí)建筑物離地下室基坑支護(hù)邊距離約10~13米左右，原地面絕對(duì)標(biāo)高約9.8~10米；基坑?xùn)|側(cè)及東北側(cè)為已經(jīng)開(kāi)挖一層地下室的基坑，標(biāo)高約為絕對(duì)標(biāo)高9米；整體場(chǎng)地情況較好，沒(méi)有影響基坑支護(hù)工程施工的場(chǎng)內(nèi)及場(chǎng)外建筑物、管線、電纜等。2、本工程基本已完成施工場(chǎng)地的“三通一平”工作，并提供建筑物定位控制點(diǎn)、臨時(shí)施工用電、臨時(shí)施工用水接駁口。第二章第二章編制說(shuō)明及依據(jù)編制說(shuō)明
