地基處理的方法

1、 換填法

假如地(di)(di)基的(de)(de)持力(li)層(ceng)比(bi)較軟(ruan)弱，沒有辦(ban)法滿足(zu)建(jian)筑物對地(di)(di)基的(de)(de)要求的(de)(de)時候(hou)，一般都會使用換土(tu)(tu)墊層(ceng)的(de)(de)方(fang)法來處理(li)地(di)(di)基。也就是在一定的(de)(de)范圍內把地(di)(di)基的(de)(de)土(tu)(tu)層(ceng)挖空(kong)掉(diao)，然后在挖空(kong)位置填滿強度更大的(de)(de)砂子(zi)、泥土(tu)(tu)、碎石等等，并且會把這些東西夯實得非(fei)常密(mi)實。

2、 預壓法

在(zai)建(jian)造房屋之(zhi)前，先在(zai)施工場(chang)地(di)上(shang)施加(jia)或者是分級(ji)施加(jia)和地(di)基(ji)相當的荷載，讓(rang)地(di)基(ji)土(tu)(tu)(tu)層空隙中的水被擠壓出來，讓(rang)土(tu)(tu)(tu)層空隙變(bian)得(de)(de)更小，讓(rang)地(di)基(ji)土(tu)(tu)(tu)層變(bian)得(de)(de)更加(jia)的密(mi)實，從而把地(di)基(ji)的承(cheng)載能(neng)力和穩定性變(bian)得(de)(de)更強。

3、 強夯法

把幾十噸的重錘從高(gao)處重重的落在地(di)基(ji)上(shang)，如此反復操作，不(bu)斷的對(dui)地(di)面進行強力(li)的夯(hang)擊，讓地(di)基(ji)直接被夯(hang)實(shi)得非常密實(shi)。一般(ban)情況下，經過強力(li)夯(hang)實(shi)的地(di)基(ji)可(ke)以提(ti)高(gao)2倍(bei)到5倍(bei)左右的承載力(li)，而壓縮(suo)性則會被降(jiang)(jiang)低到200%到500%之間(jian)，地(di)基(ji)深度則會被下降(jiang)(jiang)10米(mi)左右。

4、振沖法

利用振(zhen)(zhen)動器不斷的(de)在地(di)基(ji)(ji)中進行加水和振(zhen)(zhen)動，讓(rang)(rang)土層(ceng)(ceng)空隙變(bian)得(de)更(geng)小，讓(rang)(rang)地(di)基(ji)(ji)土層(ceng)(ceng)變(bian)得(de)更(geng)加的(de)密(mi)實，從(cong)而(er)改善(shan)地(di)基(ji)(ji)狀態，讓(rang)(rang)地(di)基(ji)(ji)可以滿足建筑物對地(di)基(ji)(ji)的(de)施工要求。振(zhen)(zhen)沖(chong)(chong)法全(quan)稱叫做振(zhen)(zhen)動水沖(chong)(chong)擊法，一般可以被分為(wei)振(zhen)(zhen)沖(chong)(chong)置換法和振(zhen)(zhen)沖(chong)(chong)密(mi)實法兩種，大(da)家(jia)可以根據地(di)基(ji)(ji)土層(ceng)(ceng)的(de)不同(tong)來進行選擇。

擠密樁施工排水措施

　1、基坑施工過程中(zhong)對(dui)地表水(shui)(shui)(shui)(shui)(shui)控(kong)制，以便(bian)進行排(pai)水(shui)(shui)(shui)(shui)(shui)措施調整，對(dui)地表滯(zhi)水(shui)(shui)(shui)(shui)(shui)進行如下控(kong)制：沿(yan)基坑周邊防護(hu)欄(lan)處(chu)設置一(yi)明排(pai)水(shui)(shui)(shui)(shui)(shui)溝(gou)，為了排(pai)除雨(yu)季的(de)暴雨(yu)突然而來的(de)明水(shui)(shui)(shui)(shui)(shui)，防止(zhi)排(pai)水(shui)(shui)(shui)(shui)(shui)溝(gou)泄水(shui)(shui)(shui)(shui)(shui)不及，特在基坑一(yi)側設一(yi)積水(shui)(shui)(shui)(shui)(shui)池，再(zai)通(tong)過抽水(shui)(shui)(shui)(shui)(shui)泵(beng)及時將積水(shui)(shui)(shui)(shui)(shui)抽至到河邊進行排(pai)水(shui)(shui)(shui)(shui)(shui)，做(zuo)到有組織排(pai)水(shui)(shui)(shui)(shui)(shui)，確保(bao)排(pai)水(shui)(shui)(shui)(shui)(shui)暢通(tong)。

　2、基(ji)坑(keng)(keng)排水(shui)措施基(ji)坑(keng)(keng)上邊排水(shui)溝的水(shui)統一排至基(ji)坑(keng)(keng)周邊沉淀池，然后(hou)就(jiu)近排向廠區雨水(shui)井內。

　3、基坑降水(shui)措施基坑明水(shui)滲入底板下礫沙層，全部用深井泵排出，確(que)保基坑無積(ji)水(shui)。
