地下连续墙深基坑开挖综合特性研究

本文在前人研究成果及笔者近年来工作的基础上,对软土地基地下连续墙作挡墙的深开挖理论进行了较为详细的研究,包括基坑周围地层变位机理研究、地表沉降与墙体侧移的预估、稳定性与地表沉降的关系、支撑轴力的预测、改善基坑受力及变形特性的具体施工措施和现场实测结论等等。本成果可供软土地区深基坑开挖的性态分析作参考。

General Behaviours of Deep Excavation with Diaphragm Wall

Results of research on deep excavation with diaphragm wall as retaining wail in soft clay is presented, which include mechanism of ground displacement around pit, prediction of ground settlement and lateral movement of wall relationship between ground settlement and stability, estimation of axial forces in struts and relevant construction methods which can improve the loading condition and deformation of excavation. The results can be used as reference for the analysis of deep exacavation in soft clay.
