地基處理的方法

1、 換填法

假如地基的持力(li)層(ceng)比較軟弱，沒(mei)有辦法滿足建筑物對地基的要求的時(shi)候(hou)，一般都會使用換土(tu)墊層(ceng)的方法來處理(li)地基。也就是在一定(ding)的范圍內把地基的土(tu)層(ceng)挖(wa)空掉(diao)，然后在挖(wa)空位(wei)置填滿強度更(geng)大的砂子、泥土(tu)、碎石(shi)等(deng)等(deng)，并且(qie)會把這些東(dong)西(xi)夯實(shi)得非常密實(shi)。

2、 預壓法

在(zai)建(jian)造房屋(wu)之(zhi)前，先在(zai)施工場(chang)地(di)(di)上施加或(huo)者(zhe)是分(fen)級(ji)施加和地(di)(di)基(ji)(ji)相當的荷(he)載，讓地(di)(di)基(ji)(ji)土(tu)層(ceng)空隙(xi)中(zhong)的水被(bei)擠壓出(chu)來，讓土(tu)層(ceng)空隙(xi)變(bian)得更(geng)小，讓地(di)(di)基(ji)(ji)土(tu)層(ceng)變(bian)得更(geng)加的密實(shi)，從而把地(di)(di)基(ji)(ji)的承載能力和穩定性(xing)變(bian)得更(geng)強(qiang)。

3、 強夯法

把(ba)幾十噸(dun)的(de)(de)重(zhong)錘(chui)從(cong)高處(chu)重(zhong)重(zhong)的(de)(de)落在地(di)基(ji)上，如此反(fan)復操(cao)作，不斷的(de)(de)對地(di)面進(jin)行強力的(de)(de)夯擊(ji)，懷仁擠密樁施(shi)工，讓地(di)基(ji)直接被(bei)夯實(shi)得非常密實(shi)。一般情況下(xia)(xia)，經過強力夯實(shi)的(de)(de)地(di)基(ji)可以提高2倍到5倍左右的(de)(de)承載(zai)力，而壓縮性(xing)則(ze)會(hui)被(bei)降低到200%到500%之間(jian)，地(di)基(ji)深(shen)度(du)則(ze)會(hui)被(bei)下(xia)(xia)降10米左右。

4、振沖法

利(li)用(yong)振動器不斷的(de)在地基中進行加(jia)水和振動，讓(rang)土(tu)層空(kong)隙變得更(geng)小(xiao)，讓(rang)地基土(tu)層變得更(geng)加(jia)的(de)密實，從而改善(shan)地基狀態(tai)，讓(rang)地基可以滿足(zu)建筑物(wu)對地基的(de)施工(gong)要求。振沖法全稱叫做振動水沖擊法，一般可以被分(fen)為振沖置(zhi)換法和振沖密實法兩種，大家(jia)可以根據(ju)地基土(tu)層的(de)不同(tong)來進行選擇。
