| 摘 要： | 某热轧带钢工程旋流沉淀池基坑深39.3 m,采用圆形地下连续墙作为支护结构,介绍了该地下连续墙设计方案,利用三维有限元对其受力和变形进行了分析。计算表明:分层逆作法施工内衬墙对地下连续墙的变形影响很大,没有内衬墙时地下连续墙变形增加一倍。分析表明:双向承压加直线段成承弯假设计算环向压力偏于安全。

| Abstract: | A foundation pit engineering using circle-style retaining structures was introduced.The design of diaphragm walls was summarized.The retaining structures were modelled by the three-dimensional elastoplastic finite element method.It is shown by numerical analysis that the lining-wall is critical for the safety of diaphragm and the displacement of diaphragm will be doubled without lining-wall.It is also shown by analysis that the design of diaphragm is conservative. |
