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。
Based on the field test and the concept of space-time effect of foundation pit engineering, the stress-bearing characteristics of the pile-anchor supporting system during the excavation of deep foundation pit were studied and the distribution of earth pressure in the active area with excavation conditions was obtained .
