REVIEW AND PROSPECT OF RESEARCH ON DEFORMATION MECHANISMS OF DEEP FOUNDATION GROUND CONNECTING WALLS IN SOFT SOIL AREAS

随着城市化进程的加速和地下空间利用的增加,不同土质环境下深基坑工程中维护结构的变形性状及稳定性控制存在差异,如何精确评估和预测软土地区深基坑工程中地下连续墙的变形行为是关键挑战之一。通过回顾近年来对软土地区深基坑工程中地下连续墙的变形机理研究,综合分析软土土质特性对深基坑地下连续墙位移变形的影响,总结不同案例中的变形规律,探讨有效的预测模型规律和策略。

With the acceleration of urbanization and the increase of underground space utilization,there are differences in the deformation properties and stability control of maintenance structures in deep foundation pit projects under different soil environments,and how to accurately assess and predict the deformation behavior of diaphragm walls in deep foundation pit projects in soft soil areas is one of the key challenges.By reviewing the deformation mechanism research on diaphragm walls in deep foundation pit projects in soft soil areas in recent years,we comprehensively analyze the influence of soft soil properties on the displacement and deformation of diaphragm walls in deep foundation pits,summarize the deformation laws in different cases,and explore the effective prediction model laws and strategies.
