摘要:
文章结合哈大铁路客运专线工程岩溶地区的桥梁柱桩基础设计,利用有限元分析软件Midas,计算了岩溶区柱桩基础下岩石应力分布情况,分析了不同桩径下溶洞顶板的最大剪应力及最大主拉应力,确定了岩溶区桥梁柱桩基础下溶洞顶板的安全厚度设计原则,解决了岩溶地区桥梁多层溶洞柱桩基础设计难题。其内容可作为今后铁路客运专线岩溶区桥梁柱桩基础设计的参考。
Abstract:
In this paper, combined with the bridge column pile foundation design in the karst area of Harbin-Dalian Passenger Dedicated Line and using finite element analysis program Midas, a calculation on the rock stress distribution under column pile foundation in the karst area is made, an analysis is made on the maximum shear stress and the maximum main tensile stress of cave roof under the condition of different pile diameter, the safety thickness design principle of karst cave roof under column pile foundation of the bridge in the karst area, and the design problem of column pile foundation in multilayer karst caves is resolved. The paper can be used for column pile foundation design of bridge on passenger dedicated line project in karst area for reference in the future.
