摘要:
选取柔性挡墙典型位移曲线为研究对象,将土体看作是一系列弹簧和理想刚塑体的组合体,引入非线性土弹簧模型,建立土压力与围护结构水平位移的耦合关系,并将其与弹性地基梁法结合.采用有限差分法求解基坑开挖随土压力改变引起的围护结构水平位移,对不同工况下土压力及地下连续墙侧向位移与现场实测值进行对比.结果表明:计算值与现场实测值随墙高方向及位移大小的变化规律基本一致;随着基坑开挖深度的增加,地下连续墙的水平位移曲线会逐渐变成鼓型曲线.
Abstract:
The typical displacement curves of flexible retaining wall are selected as the research objects, and the soil is regarded as a combination of a series of springs and ideal rigid-plastic body. Combining with the elastic foundation beam method, the nonlinear soil spring model is introduced to establish the coupling relationship between earth pressure and horizontal displacement of retaining structure. The finite difference method is used to solve the horizontal displacement of retaining structure caused by the excavation of foundation pit with the change of earth pressure. The earth pressure and the lateral displacement of the underground continuous wall under different working conditions are compared with the field measured values. The results show that the calculation values are basically consistent with the measured values in the direction of wall height and displacement magnitude. As the excavation depth of the foundation pit increases, the horizontal displacement curves of the underground continuous wall will gradually become a drum shaped curves.
