广西裸露型岩溶山区铁路隧道岩溶综合勘察

Comprehensive Inspection of Railway Tunnel in Exposed Karst Mountainous Areas in Guangxi

结合广西某铁路隧道勘察,介绍了裸露型岩溶峰丛地区岩溶综合勘察的工作思路、工作布置、成果综合分析,特别是介绍了利用近年来快速发展的电磁法和高精度重力法探测技术进行综合物探探测,阐述了多方法的优越性可以弥补单一方法的不适用,且综合解释可以克服多解性,总结出适合于裸露型岩溶峰丛地区的隧道岩溶勘察的方法组合并提出实施建议。

Based on the survey of a railway tunnel in Guanxi Province, the exposed Karst Peak are introduced from the working principles, work arrangement, result analysis of the regional Karst comprehensive survey. The electromagnetic survey and extra accuracy gravitational condensation prospecting that were adopted to implement the comprehensive geophysical detections are specially introduced. The advantage of multi-method in making up the inapplicability of the single-method and comprehensive interpretation in overcoming the multiplicity solutions are introduced as well. The combined way of Karst tunnel survey that is suitable to the Karst Peak Clumped area is summarized and the implementation proposals are also pro- posed in the article.
