1.提高地(di)基土的抗剪切強(qiang)度

地(di)(di)基(ji)(ji)(ji)(ji)的(de)剪(jian)(jian)切破壞(huai)表現在：建(jian)筑物的(de)地(di)(di)基(ji)(ji)(ji)(ji)承載力不夠(gou)；由于(yu)偏心荷載及側(ce)向土(tu)(tu)壓力的(de)作用使(shi)結構物失穩(wen)；由于(yu)填土(tu)(tu)或建(jian)筑物荷載，使(shi)鄰近地(di)(di)基(ji)(ji)(ji)(ji)產生隆起；土(tu)(tu)方(fang)開挖(wa)時邊坡(po)失穩(wen)；基(ji)(ji)(ji)(ji)坑開挖(wa)時坑底隆起。地(di)(di)基(ji)(ji)(ji)(ji)的(de)剪(jian)(jian)切破壞(huai)反映(ying)在地(di)(di)基(ji)(ji)(ji)(ji)土(tu)(tu)的(de)抗(kang)剪(jian)(jian)強(qiang)度(du)不足，因此，為了防(fang)止剪(jian)(jian)切破壞(huai)，就需要采取措施以增(zeng)加地(di)(di)基(ji)(ji)(ji)(ji)土(tu)(tu)的(de)抗(kang)剪(jian)(jian)強(qiang)度(du)。

2.降低地(di)基土的壓(ya)縮性

地(di)基土(tu)(tu)的(de)壓(ya)縮性表(biao)現在建(jian)(jian)筑(zhu)物的(de)沉(chen)降(jiang)(jiang)(jiang)和差(cha)異(yi)沉(chen)降(jiang)(jiang)(jiang)大；由于(yu)有(you)填(tian)土(tu)(tu)或(huo)建(jian)(jian)筑(zhu)物荷(he)載，使地(di)基產(chan)生固結沉(chen)降(jiang)(jiang)(jiang)；作用于(yu)建(jian)(jian)筑(zhu)物基礎的(de)負(fu)摩擦力引(yin)起(qi)建(jian)(jian)筑(zhu)物的(de)沉(chen)降(jiang)(jiang)(jiang)；大范圍(wei)地(di)基的(de)沉(chen)降(jiang)(jiang)(jiang)和不均(jun)勻沉(chen)降(jiang)(jiang)(jiang)；基坑開(kai)挖引(yin)起(qi)鄰近地(di)面沉(chen)降(jiang)(jiang)(jiang)；由于(yu)降(jiang)(jiang)(jiang)水地(di)基產(chan)生固結沉(chen)降(jiang)(jiang)(jiang)。地(di)基的(de)壓(ya)縮性反映在地(di)基土(tu)(tu)的(de)壓(ya)縮模(mo)量指(zhi)標的(de)大小(xiao)。因此，需要采取措施以提(ti)高地(di)基土(tu)(tu)的(de)壓(ya)縮模(mo)量，借(jie)以減少地(di)基的(de)沉(chen)降(jiang)(jiang)(jiang)或(huo)不均(jun)勻沉(chen)降(jiang)(jiang)(jiang)。
