| 摘 要： | 隐伏岩溶漏斗严重影响拟建工程的安全,对其开展针对性的勘察工作可为设计及施工提供科学依据。本文以水南特大桥8#墩勘察为例,介绍了采用地质雷达、高密度电法和浅层地震等3种方法探测隐伏岩溶漏斗的工作方法,查明了右幅8#墩岩溶漏斗的地表边界及基岩埋深变化特征,圈定了隐伏岩溶漏斗的范围和岩溶漏斗平面形态,取得了较好的探测效果,为桥基设计提供了指导性的基础资料。

| Abstract: | Concealed karst cone has serious influence to the safety of proposed projects.It can provide scientific basis for design and construction to start a pointed perambulation of it.Taking the perambulation of Shuinante Bridge for example,this paper introduces three operating methods adopted to probe concealed karst cone,such as geological radar,high-density electrical method and shallow seismic,and finds out the surface boundary layer of the karst cone at 8th pier on the right and the variation characters of em... |
