斜坡岩基坡度对桥梁扩大基础承载力影响的有限元分析

摘要

In the road and bridge construction in the mountainous western region, the broadened foundation of a bridge often lies on slope batholith. Dif-ferent slope batholiths density and different slopes exert different influences on the slope batholith. Based on the fact, a three-dimensional finite element numerical simulation is carried out. The calculation results under multiple conditions are compared and analyzed. Relevant conclusions can offer some references for bridge foundation engineering in mountainous regions.%　　在西部山区的公路桥梁建设中，桥梁扩大基础多落在斜坡岩基之上，不同的斜坡基岩强度，以及不同的基岩斜坡坡度，对桥梁扩大基础地基承载力也有不同的影响，基于这一课题，该文开展了三维有限元数值模拟研究，对多种情况下的计算结果进行了对比和分析，相关结论可供山区桥梁基础工程建设参考借鉴。
