桩锚支护体系的受力和变形研究

Study on behavior and deformation of supporting systems for pile-anchor

在深基坑工程中,现场实测主动、被动土压力的大小和分布与经典土压力理论完全不同,分析了产生这一现象的原因,并通过室内模型试验、平面有限元法对桩锚支护体系进行了试验和数值分析,结果表明用这2种方法研究支护结构的变形和受力性状是可行的,试验与数值计算结果较为吻合.

In deep foundation engineering,the reasons that the earth pressure value and distribution of the classical earth pressure theory which are quite different from the field measurement are analyzed.The model test and plane strain finite element are applied to the study of the behavior and deformation of supporting systems of pile?anchor.These two methods are feasibal because they can simulate the supporting and the excavation.The results of the test and numerical analysis are consistent.
