岩溶山地城市轨道交通工程勘察新模式

A New Exploration Model for Rail Transit Engineering in Karst Mountain Cities

在贵阳城市轨道交通工程建设中,岩溶作为普遍性不良地质作用,成为地质勘察面临的首要问题。通过总结贵阳市城市轨道交通岩溶勘察经验,分析现阶段岩溶勘察存在的问题和主要矛盾后,从岩溶特点和轨道交通特点出发,创新性地提出“地质调绘先行、综合物探普查、工程钻探验证、施工过程复核修正”的岩溶勘察新模式。

In the construction of Guiyang urban rail transit project,as a common adverse geological process,karst has become the primary problem faced by geological exploration.By summarizing the experience of karst exploration in urban rail transit in Guiyang,analyzing the problems and main contradictions in current karst exploration,and starting from the characteristics of karst and rail transit,a new karst exploration model of geological mapping first,comprehensive geophysical survey,engineering drilling verification,and construction process review and correction is innovatively proposed.
