摘要

岩溶塌陷是铁路工程项目建设过程中较为常见的一种地质灾害,由于其具有隐蔽性、突发性等特点,对铁路工程项目质量安全造成了重大影响。为此运用综合物探法对贵州铜仁玉屏铁路武陵山隧道铁路基底岩溶进行全面、系统探测。首先运用探地雷达法对武陵山隧道基底岩溶分布、岩溶范围、类型特点以及发育程度等进行了针对性的探测,然后运用地震映像法对检测到的结果进行验证。根据探测结果可知,应用综合物探法可基本查明铁路基底岩溶分布状态,从而更为科学地判定隧道基底岩溶各方面的情况,保证工程项目的质量安全。
        Karst collapse is a common geological disaster in the process of the railway construction. Its characteristics of concealment and suddenness have a significant impact on the safety of railway engineering. This paper adopts the integrated geophysical exploration method to conduct a comprehensive and systematical detection on the basement karst of the Wulingshan tunnel in Tongren-Yuping railway, Guizhou. The ground penetrating radar technology is applied to appropriately detect the distribution, type and development degree of karst at the bottom of the tunnel initially. Then the seismic imaging technique is used to verify the detecting results. According to the results, using the integrated geophysical exploration method can basically find out the karst distribution, which scientifically determines all sorts of karst condition in railway basement and ensures the safety of railway engineering.
