摘　　要：研究目的:近年来,由于各种地质环境问题,岩溶地区既有铁路路基时有岩溶塌陷现象发生,严重影响铁路运营与行车安全。本文为解决此类工程地质问题,通过踏勘、工程地质测绘调查、物探、钻探等综合勘察手段,对既有芜铜铁路狮子山站岩溶塌陷路基病害进行综合分析,为病害路基整治提供依据。研究结论:(1)在现场复杂的环境条件,可采用综合勘探技术获得可靠的地质资料;(2)当停止抽水后岩溶地面塌陷仍将断续发生,这种"滞后效应"的存在应引起相关人员的足够重视;(3)经过整治后的运营实践,证明本文所用勘察整治方法正确有效,效果显著,本文研究成果对类似的岩溶路基整治工程有很好的借鉴作用。Research purposes： In recent years, because of various geological environmental problems, karst collapse phenomenon frequently occurs in existing railway subgrade in karst area, and it seriously influences the railway operation and traffic safety. In order to solve such geotechnical problems, based on the field inspection, geotechnical surveying, geophysical prospecting, drilling and other comprehensive exploration methods, this paper comprehensively analyzes the karst subgrade diseases of Shizhishan Station in the existing Wuhu - Tongling Railway, and provides the basis for subgrade disease treatment. Research conclusions： （ 1 ） For the on - site complicated environmental conditions, adopt the comprehensive exploration technique to obtain the reliable geological data. （2） After the termination of pumping, karst collapse will still happen intermittently, the existence of such ＂ hysteresis effect＂ should be paid enough attention to by relative personnel. （3） The operation practice after treatment proves that the investigation and treatment methods adopted in this paper are correct and effective and have significant effect, the research results of this paper provide a good reference for the similar karst subgrade treatment projects.
