19、下室邊線距離較小，對(duì)基礎(chǔ)設(shè)計(jì)和施工造成較大困難。本工程地基基礎(chǔ)設(shè)計(jì)等級(jí)為甲級(jí)，由于地質(zhì)情況較復(fù)雜，南面T型住宅及中間M型（M6～M11棟）采用靜壓式高強(qiáng)混凝土預(yù)應(yīng)力管樁基礎(chǔ)，M12、M13及北面K戶型采用筏板基礎(chǔ)，裙樓為筏板基礎(chǔ)抗拔錨桿，K4～K7棟（～軸）為CFG剛性復(fù)合地基（長(zhǎng)○1○22螺旋鉆孔灌注樁＋樁間土＋褥墊層），K8（～軸）、M12、M13棟為天然基礎(chǔ)?！?2○30根據(jù)業(yè)主指令，基坑土方開(kāi)挖由土方專業(yè)分包單位開(kāi)挖底板底。根據(jù)

20、地質(zhì)勘察報(bào)告所示，承臺(tái)開(kāi)挖范圍的土質(zhì)大致為粘土、砂質(zhì)粘土、淤泥、淤泥質(zhì)土、全風(fēng)化基巖、局部為強(qiáng)風(fēng)化基巖，地下水類型主要有孔隙水有裂隙水，孔隙水主要賦存于②4中細(xì)砂層中，裂隙水主要賦存于⑤2強(qiáng)風(fēng)化花崗巖中，屬于強(qiáng)透水層。大氣降水和側(cè)向徑流是區(qū)內(nèi)地下水的主要補(bǔ)給來(lái)源，大氣蒸發(fā)及滲透為地下水排泄條件，地下水水位隨季節(jié)性變化。本工程承臺(tái)厚度為0.9～3.4m，大多數(shù)為1.4m以下，電梯井為3.4m；承臺(tái)土方開(kāi)挖厚度為0.5～2.9m不等。二、編
