土(tu)木工程的地基問題(ti)，概(gai)括起來有四個方面。

　1、強度(du)和穩(wen)定性(xing)問題；

　2、壓縮及(ji)不均勻沉降(jiang)問題；

　3、地基的(de)滲漏量超過允(yun)許(xu)值(zhi)，會(hui)發(fa)(fa)生水量損失(shi)導致(zhi)發(fa)(fa)生事故。

　4、、機器以及車輛(liang)的振動、波浪作用和(he)(he)等動力(li)荷載可能引起地基土，特別是飽和(he)(he)無(wu)粘(zhan)性土的液化、失穩(wen)和(he)(he)震陷等危害。

土木(mu)工程的(de)地(di)基問題處理(li)

　地(di)基處理(li)常采(cai)用的方法：

　1、采(cai)取措施(shi)使(shi)土(tu)中孔(kong)隙減少、土(tu)顆(ke)粒之間靠近，碎(sui)石擠密(mi)樁施(shi)工方案，密(mi)度加大，土(tu)得承載(zai)力提高；

　2、在地基中摻加(jia)各種物料，25米碎石擠(ji)密樁施工，通過物理化學作用(yong)把土(tu)顆粒膠結在一起，使使地基承載力提(ti)高，剛度加(jia)大、變(bian)形減(jian)小。

　砂(sha)樁(zhuang)、碎石樁(zhuang)、水泥粉煤灰(hui)碎石樁(zhuang)

　碎石樁和(he)(he)砂(sha)樁合(he)稱(cheng)為粗顆(ke)粒土樁。是指用振動、沖擊或振動水沖等方式在軟弱地基(ji)中(zhong)成(cheng)(cheng)孔，山(shan)西碎石擠(ji)密(mi)樁施工，再將碎石或砂(sha)擠(ji)壓入孔，形(xing)成(cheng)(cheng)大直(zhi)徑的由碎石或砂(sha)構(gou)成(cheng)(cheng)的密(mi)實(shi)樁體(ti)，具有擠(ji)密(mi)、置換、墊層(ceng)和(he)(he)加(jia)筋等加(jia)固作用。

　水(shui)泥粉煤(mei)灰碎石樁(zhuang)(zhuang)（簡稱CFG）是在碎石樁(zhuang)(zhuang)的基礎上加進一(yi)些石屑、粉煤(mei)灰和(he)少量水(shui)泥，加水(shui)拌合制成的具有一(yi)定(ding)強度的樁(zhuang)(zhuang)。樁(zhuang)(zhuang)的承載力(li)來自(zi)樁(zhuang)(zhuang)全(quan)長(chang)產生的摩阻(zu)力(li)及(ji)樁(zhuang)(zhuang)端承載力(li)，適用(yong)于多層和(he)高層建筑地(di)基。
