摘要
在参考已有资料的基础上 ,分析了山区城市浅埋地下洞室安全顶板厚度的影响因素。采用有限单元数值模拟法研究了基础与洞室相互作用下的破坏机制 ,以及各影响因素对浅埋地下洞室安全顶板厚度的影响及相关变化规律。并运用逐步线性回归的方法得出了一个能综合考虑各影响因素的安全顶板厚度的预测模型。
The factors affecting the safety thickness of top plate above shallow buried cavities in mountaunous city are studied based on the existent data referred. The failure mechanism of interaction process between the foundation and cavity and, the effect of every factor on safe thickness of top plate are studied by FEM simulation. A forecast model of safe thickness of top plate, which can consider all the factors, is obtained by stepwise regression analysis.
