| 摘 要： | 在上海某车站基坑地下连续墙的逆作法施工中,参考以往上海软土地区的工程经验对该工程中土压力的计算方法和土压力分布模式选取进行了研究。通过实地监测与计算分析所得结果进行比较,发现在浅挖时采用三角形+矩形土压力模式计算的弯矩值比较真实的反映了工程实际,而采用三角形土压力模式计算的弯矩明显与实际不符,造成基坑面以下弯矩包络图数值偏大。

| Abstract: | In this paper,based on the construction experience of soft ground in Shanghai,the calculation method of soil pressure and the selection of soil pressure distribution pattern were analyzed.The diaphragm wall was builded in the topdown construction.The horizontal displacements and the depth of the maximum horizontal displacements were measured in site.Compared with the results of calculation,the moment values calculated by using the rectangle pattern of soil pressure have a better simulation of the actual sit... |
