岩溶区隧道暗河的综合预报及治理方案研究
|
摘要
为确保岩溶区隧道施工安全,利用综合预报分析方法可准确地对地质异常体进行预测,可明显减少发生灾害的可能性。以大广南高速公路紫荆山隧道为工程背景,通过地质分析研究了紫荆山隧道的岩溶发育特征,利用TSP(隧道地震预测)超前地质预报方法对ZK221+960处暗河位置进行了准确预报,并利用地质雷达对暗河的走向进行了短距离探测,探测结果与实际揭露走向基本吻合。针对紫荆山暗河,分析了各种暗河处治措施优缺点,最终制定了泄水洞方案。在保证隧道施工安全和工期的前提下,对泄水洞方案进行了优化处理,优化后的处理方案在紫荆山暗河治理中取得了较好的效果,其结果对类似工程具有一定的借鉴意义。
In order to ensure the construction safety of karst tunnel,the unfavorable geological body can be accurately predicted using integrated prediction method so as to significantly reduce the potential for disasters.Setting the Zijingshan Tunnel of the Da-Guang'nan Expressway as the project background,firstly,the developing characteristics of the karst of Zijingshan Tunnel is studied through geological analysis.And then,long-distance detection of unfavorable geology is done with the TSP(tunnel seismic prediction) method;so an accurate prediction of the ZK221+960 underground river's location is obtained;and a short detection of the underground river's direction is done using geological penetrating radar.The detection result is consistent with actual disclosure direction.For the actual situation of Zijingshan Underground River,drainage tunnel program is eventually made after many analysis of various treatment program.Under the premise of ensuring the safety and duration of tunnel construction,the hole drainage program is optimized.The optimized processing program achieves good results in the Zijingshan Underground River's governance,which has some reference significance for the similar engineering.
