摘　　要：[目的]在贵阳城市轨道交通工程勘察中,岩溶是具有普遍性的不良地质,是地质上面临的首要问题。当今岩溶问题的勘察模式同贵阳城市轨道建设的需求是不相匹配的,故必须探索一种适用于岩溶山地城市轨道交通建设的岩溶勘察模式。[方法]从岩溶危害出发,总结分析岩溶勘察的技术手段、规范约束和贵阳市的实际经验共三个方面的内容后,明确指出现阶段采用的“工程地质调绘先行,工程钻探为主,工程物探为辅”的岩溶勘察模式是历史所形成的,并论述了当前轨道交通山地岩溶勘察的主要矛盾是对岩溶勘察的高分辨率要求与勘察方法的低分辨率水平之间的矛盾。[结果及结论]从现阶段岩溶勘察的主要矛盾出发,根据岩溶勘察技术手段的发展,结合具体案例分析,经研究提出:“工程地质调绘先行,工程钻探为主,工程物探为辅”的岩溶勘察模式必将走向“从工程需要出发,以地质思维为指导,地质调绘先行,地面物探普查,钻探和钻孔物探为补充和验证,多方法综合”的新勘察模式。[Objective]In the geological survey for Guiyang urban rail transit projects,karst is a common unfavorable geological condition and also the top geological issue to be confronted.However,the current survey mode of karst problems does not match the demand of Guiyang urban rail transit construction.Therefore,it is necessary to explore a karst survey mode applicable for urban rail transit construction in karst mountainous city.[Method]Starting from the karst hazards,the technical means,normative constrains and the actual experience from Guiyang City about karst survey are summarized and analyzed.It is then clearly pointed out that the current karst survey mode with“engineering geological mapping first,engineering drilling as the main method,engineering geophysical prospecting as the secondary method”is formed in the course of history,the situation where the contradiction between high resolution requirements and low resolution levels of the karst survey method becomes the principal one in current mountain karst survey for rail transit is discussed.[Result&Conclusion]Starting from the main contradiction in the current karst survey,and based on the development of technical means in karst survey and specific case analysis,it is concluded through research that the above-mentioned karst survey mode will inevitably evolve into a new survey mode of“starting from engineering needs and guided by geological thinking,with geological mapping first,ground geophysical survey,drilling and borehole geophysical prospecting as supplement and verification,featuring multi-method integration”.
