地下连续墙与地下结构外墙两墙合一模型试验研究

地下连续墙与地下结构外墙"两墙合一"的不断应用和发展,使许多工程既确保了工程质量和进度,又减小了结构断面、节省了混凝土用量。为了研究"两墙合一"后的力学性状及基础的沉降问题,利用模型试验将两墙合一模型与两墙分离模型进行比较得出,两墙合一模型:墙体的弯矩较小;随着荷载的增加,墙体弯矩的变化不明显;箱形基础的沉降在相同荷载作用下明显减小。

Modeling test study of underground diaphragm wall and box foundation external wall combined as one

Along with the application and development of underground diaphragm wall that combined with basement external wall as one. So many projects that have ensured the quality and progress of the work have also reduced the structure of the section and saved the amount of concrete. We compared the two walls into one model with the two walls separate model, the result was that the bending moment of the wall that combined with two is small, and along with the load＇s increase, the change of wall＇s bending moment is not obvious ; the settlement of box foundation is obviously reduced under the same load function.
