摘　　要：通过现场试验,围绕基坑工程时空效应理念,研究分析了在深基坑开挖过程中桩锚支护体系的受力特性,得出了主动区土压力随开挖工况而变化的分布规律。Through field tests, on the basis of the concept of space and time effect, the features of forces acting on the pile supporting system in the excavation process of deep foundation pit are studied and the distribution variation of the soil pressure in the active zone with construction process is found out.

关 键 词：土力学 桩锚支护 时空效应 主动区土压力
