摘要
在不影响铁路正常运营和安全条件下彻底处理隧道岩溶水,是亟待研究与解决的难题。首先,根据降雨量和涌水量监测,采用理论计算和数理统计分析方法测算涌水量规律;其次,通过综合超前地质预报准确判断地质条件,以指导设计和施工;再精确计算装药量控制爆破,强化过程监控测量和施工组织,保证既有行车设备、隧道衬砌和行车安全;然后,健全运营监控体系;最后,总结铁路营业线隧道隐伏高压岩溶裂隙水处理方法和控制关键点。
It is urgent to study and solve the problem that the tunnel karst water should be thoroughly treated without affecting the normal operation and safety of the railway. Firstly, according to the monitoring of rainfall and gushing discharge,the law of gushing discharge is calculated by theoretical calculation and mathematical statistic analysis. Secondly,accurate judgment of geological conditions through the comprehensive geology forecast,to guide the design and construction. Thirdly,accurately calculate the amount of charge to control blasting,strengthening process monitoring measurement and construction organization,to ensure that the existing equipment of railway,tunnel lining and traffic safety,then improve the operation monitoring system. In the end,the key point of karst fissure water treatment method and key points of hidden high pressure karst fissure in railway tunnel are summarized.
