复合土钉支护数值模拟与实测分析

Numerical simulation and site measurement analysis of the deformation of composite soil nailing system

应用FLAC软件结合某基坑施工实例,对微型桩和部分预应力复合土钉支护下的基坑进行数值模拟。分析了该支护形式在现场非均质土层中的受力特点,与实测数据的对比结果表明,FLAC对该支护形式的模拟对今后的工程实践具有一定的预测性。

In this paper, an excavation of pit braced by micro-pile and partly pri-stressed soil nail is simulated to study the mechnical properties of the supporting system. By comparison between numerical analysis result and site measurement data, the conclusions from the analysis by FLAC might be used for the prediction of the analogous engineering practice.
