underwater pile driving-
West rail, phase i, is the largest single civil engineering project to be undertaken in hong kong since the completion of the government s airport core programme
工程進行期間,需要在土質極不理想的土地打樁,包括地下溶洞、排水道及容易發生水浸的地區。By controlling the stress value of under - lying layer less than tits structure yield stress value, a new design method to decrease composite ground settlement is suggested. and the composite foundation settlements of 12 buildings with the deep mixing cement piles is calculated, which is in good accord well with the measurement in field. second, considering the influence of well resistance, smear effect and structure breakage of thick soft clay, the equivalent calculation method is proposed
首先,結合溫州地區深厚軟土,通過對室內常規試驗結果的分析,發現軟土具有較強的結構性,並給出室內固結壓縮曲線校正的新方法;提出了通過控制未打穿水泥攪拌樁復合地基下臥層的應力水平,使其小於土體結構屈服應力,以大幅度減小沉降的復合地基設計方法,並通過與12幢住宅樓未打穿水泥攪拌樁復合地基的實測沉降對比,得到了良好的驗證,進一步完善了結構性軟土壓縮變形的計算方法。According to the test results, the deformation characteristics of level soft - soil foundation and slope soft - soil foundation under the load of embankment are analyzed. the effects of driven piles and stabilizing piles reinforcements are compared. the respective influence of the two reinforcement means upon foundation deformation is discussed and useful suggestions on how to use the two means are finally put forward
根據試驗結果,分析了水平軟弱土地基與斜坡軟弱土地基在路堤荷載作用下的變形特性;比較了打入樁加固與抗滑樁加固的效果;探討了兩種加固方案的對地基變形的影響,並對兩種加固措施的使用提出了建議。
