桥梁跨越隧道内大型溶洞的处治方案研究

Study on the Treatment Scheme for Bridge Overpassing Large Karst Caverns in Tunnels

以实际工程为例,基于其水文地质专题研究,对溶腔围岩进行锚喷防护,通过方案比选后采用桥梁形式跨越溶洞,并应用Midas Civil有限元软件对桥梁进行结构安全分析计算。

Taking practical engineering as an example,based on its hydrogeological monographic study,the surrounding rock of the cavity is protected by anchoring and shotcreting.After scheme comparison,the bridge is used to span the cave,and the structural safety of the bridge is analyzed and calculated with Midas Civil finite element software.
