| 摘 要： | 地下连续墙下设置支腿,可解决其插入深度或入岩深度过长引起的施工困难和成本提高问题,性价比高。针对带支腿地下连续墙结构进行了三维有限元分析和研究,并将成果应用于杭州黄龙饭店新建工程中。在地下墙不入基岩且坑底插入深度仅2～4m时,在地下连续墙墙幅底端设置支腿,支腿承担部分水平荷载,同时满足围护结构插入深度要求,取得了成功。带支腿地下连续墙的成功应用,大大降低了施工难度和工程造价,经济效益显著。

| Abstract: | The cost will be very high when the diaphragm wall inserts rock too long.At the same time,it is difficult to construct.So Leg-support diaphragm wall is researched to solve the above problem by 3D finite element analysis.Diaphragm wall of Huang-long project with 20m-depth excavation didn’t enter into rock stratum because of prohibitive costs.To ensure diaphragm wall’s stability and safety in the situation of 2m insertion depth,two concrete legs are set up under the bottom of the wall successfully. |
