摘要
岩溶地基对桥梁的危害性非常大 ,设计与施工时必须高度重视。通过某铁路大桥溶洞桩基设计及施工 ,结合岩溶地质发育形态 ,总结岩溶发育地区桥梁基础地质勘探、洞顶板安全厚度计算、桩基设计及施工等应注意的问题 ,确保桥梁建设及运营的安全。
Karst subgrade is very detrimental to bridge that c alls for high attention in design and construction. Based on pile foundation des ign and construction in Karst cavern for a railway bridge, and geological charac teristics of the cavern, a summary was made of such issues as geological prospec t for bridge foundation, safety thickness of top slab of cavern, and pile founda tion design and construction.
