土钉支护设计中最危险滑动面确定方法的应用

The Research on the Most Dangerous Sliding Surface of the Soil Nailing Support

针对现有基坑支护最危险滑动面计算方法中存在的缺点,运用泰勒经验图表法并结合"36度线"法确定了某土钉支护设计中的最危险滑动面,且采用FLAC3D数值模拟进行对比分析,有效克服了理论方法的不足;还对原基坑支护方案进行了优化,为土钉支护工程设计提供了一种新思路。

For the faults exist in calculation on the most dangerous sliding surface in foundation, using Taylor＇s experience chart, combining ＂36-degree line＂ to get the most dangerous slip surface, this method uses FLAC3D numerical simulation to contrast and analyze, overcome the lack of theoretical method effectively, and it optimizes the supporting schemes of the foundation that provide a new way for the design of the soil nailing support.
