基(ji)底標(biao)高(gao)不符合要(yao)求現象：

　(1)基(ji)(ji)槽(坑(keng))底標高不符合設(she)計規定值，造成淺基(ji)(ji)礎(chu)埋置深(shen)度不足或超挖。

　(2)基底持力(li)層土質不符合設計要求(qiu)，或被人(ren)工擾動(dong)，造成持力(li)層承載能力(li)降低。

　1. 原因分析：

　(1)測量放線(xian)錯(cuo)誤(wu)，造(zao)成(cheng)基底標高不足(zu)或過深。

　(2)地質(zhi)勘(kan)察資料與實(shi)際(ji)情況不符(fu)，雖已挖至設(she)計(ji)規定深度，但土(tu)質(zhi)仍(reng)不符(fu)合設(she)計(ji)要求。

　(3)選(xuan)用的施工(gong)(gong)機械和施工(gong)(gong)方法(fa)不當，造成超挖。

　2. 預防措施：

　(1)當發現(xian)控制樁或標(biao)志(zhi)板有被碰(peng)撞和移動(dong)跡象時(shi)，應復查(cha)校正(zheng)，防止標(biao)高出(chu)現(xian)過大(da)誤差。

　(2)防(fang)止超挖。采用(yong)機(ji)械開(kai)挖基槽(坑)時，可(ke)在基底標高(gao)以上預留一層(ceng)土用(yong)人工(gong)清理，其厚(hou)度應根據施(shi)工(gong)機(ji)械確定。

　(3)基槽(坑)挖至基底(di)標(biao)高后，應會(hui)同設計單位、監理單位(或建設單位)檢(jian)查基底(di)土質是(shi)否符(fu)合(he)要求，并(bing)作出隱蔽工程記錄。

　3. 治理方法：

　(1)當開挖深度達到(dao)設(she)計規(gui)定，而土質不(bu)符合設(she)計要求時，應(ying)會(hui)同設(she)計單位協商處理。

　(2)如個(ge)別(bie)地方超(chao)挖時，應(ying)用與基土(tu)相同的(de)土(tu)料(liao)填補(bu)，并夯實至要(yao)求的(de)密實度，或用碎石(shi)類土(tu)填補(bu)并夯實。在(zai)重要(yao)部(bu)位超(chao)挖時，可用低強度等(deng)級(ji)混凝土(tu)填補(bu)，并應(ying)取(qu)得(de)設計單位同意(yi)。

碎石樁的質量檢驗：

對飽和粘性土應待孔隙(xi)水壓力基(ji)本消散(san)后進行，間隔時間不少于1-2周，對其他土可在(zai)施(shi)工結束后3-5天(tian)進行。

碎(sui)石樁(zhuang)(zhuang)的施工(gong)質量檢(jian)(jian)驗采(cai)用單樁(zhuang)(zhuang)荷載試驗。檢(jian)(jian)驗數(shu)量為樁(zhuang)(zhuang)數(shu)的0.5％，且不(bu)少于2根。對樁(zhuang)(zhuang)體(ti)采(cai)用靜(jing)力觸探(tan)或動力觸探(tan)進(jin)行(xing)隨即檢(jian)(jian)驗，對樁(zhuang)(zhuang)間土(tu)可采(cai)用標準貫入，靜(jing)力觸探(tan)或動力觸探(tan)等方法進(jin)行(xing)檢(jian)(jian)測(ce)，檢(jian)(jian)測(ce)數(shu)量不(bu)得少于孔樁(zhuang)(zhuang)總數(shu)的2％，以滿(man)足設計要求。

碎(sui)石樁地(di)基(ji)通過質量檢驗(yan)且碎(sui)石樁復合(he)地(di)基(ji)承(cheng)載力達到設計要求時既不小于180Kpa，方可(ke)進行路堤填筑(zhu)。路堤填筑(zhu)應嚴格控(kong)制填筑(zhu)速率，控(kong)制標(biao)準為：路堤中(zhong)心線地(di)面沉降速率每晝(zhou)夜(ye)不大于1厘(li)米，坡腳(jiao)水平位移率每晝(zhou)夜(ye)不大于0.5厘(li)米。若有異常，山西擠(ji)密(mi)樁施(shi)工費用，應停止或暫緩填筑(zhu)。

振沖法(fa)(fa)。在(zai)(zai)軟土地(di)基中應(ying)用(yong)振沖法(fa)(fa)，山西擠(ji)密樁施工，就(jiu)是(shi)在(zai)(zai)地(di)基中嵌入一根根砂石樁柱，形(xing)(xing)成一種(zhong)復合地(di)基，這(zhe)種(zhong)地(di)基的(de)承載(zai)力(li)標(biao)準應(ying)根據現場(chang)復合地(di)基荷載(zai)試驗確定。振沖法(fa)(fa)就(jiu)是(shi)利用(yong)振沖器的(de)振動力(li)和(he)水沖作用(yong)形(xing)(xing)成連(lian)續的(de)孔洞，直至設計的(de)加固深度(du)。

渣(zha)土樁法。在(zai)加(jia)固(gu)(gu)(gu)過程(cheng)中，由于重(zhong)錘的(de)(de)沖擊(ji)(ji)能造成(cheng)一(yi)系列(lie)壓(ya)(ya)(ya)縮(suo)波，使土體(ti)內出現排(pai)水(shui)網絡，土的(de)(de)滲透性驟然增(zeng)大(da)，孔(kong)隙水(shui)迅速(su)排(pai)出，孔(kong)隙壓(ya)(ya)(ya)力(li)很快(kuai)消散，從(cong)而(er)產(chan)生瞬時(shi)沉降(jiang)，使土體(ti)壓(ya)(ya)(ya)密(mi)，強(qiang)度提高;同時(shi)重(zhong)錘的(de)(de)沖擊(ji)(ji)作用使填(tian)料向夯擊(ji)(ji)方(fang)向和側向擠密(mi)，從(cong)而(er)對其周圍的(de)(de)土體(ti)產(chan)生擠密(mi)加(jia)固(gu)(gu)(gu)作用，形成(cheng)一(yi)個自內向外的(de)(de)擠密(mi)圈。在(zai)擠密(mi)過程(cheng)中，周圍土體(ti)的(de)(de)孔(kong)隙水(shui)壓(ya)(ya)(ya)力(li)隨之，形成(cheng)超靜孔(kong)隙水(shui)壓(ya)(ya)(ya)力(li)。根據巴倫固(gu)(gu)(gu)結原理因為固(gu)(gu)(gu)結時(shi)間與(yu)排(pai)水(shui)距(ju)離的(de)(de)平方(fang)成(cheng)正比，所以，增(zeng)加(jia)排(pai)水(shui)途徑，縮(suo)短排(pai)水(shui)距(ju)離，才能加(jia)速(su)軟土固(gu)(gu)(gu)結，提高地(di)(di)基(ji)承載力(li)。加(jia)固(gu)(gu)(gu)柱體(ti)本(ben)身與(yu)軟基(ji)有不同強(qiang)度，它(ta)既(ji)是(shi)軟土固(gu)(gu)(gu)結的(de)(de)排(pai)水(shui)體(ti)，又是(shi)基(ji)礎(chu)的(de)(de)渣(zha)土樁。渣(zha)土樁和擠密(mi)后的(de)(de)地(di)(di)基(ji)土共(gong)同組成(cheng)復合地(di)(di)基(ji)，從(cong)而(er)提高地(di)(di)基(ji)強(qiang)度并減小地(di)(di)基(ji)變形。
