特殊结构大跨径桥梁的桥位岩溶地质评价及稳定性分析

Karst Geological Assessment of Bridge Site and Stability Analysis of Large-span Bridge with Special Structure

以某特殊结构大桥工程地质勘察为例,阐述了岩溶地区桥址详勘阶段采用工程地质调绘、钻探、室内岩土试验等多种勘察、测试手段,对桥位区岩溶的发育情况及稳定性作出准确的评价与分析,为后续的设计及安全施工提供了可靠资料。

Taking the engineering geological investigation of a bridge with special structure as an example,many kinds of exploration and testing methods,such as engineering geological mapping,drilling,indoor geotechnical test are used in the detailed exploration stage of bridge site in Karst area to accurately evaluate and analyze the development and stability of karst in the bridge site,so as to provide reliable information for the follow- up design and safety construction.
