摘要:
灰岩地层经过水溶蚀作用后，会形成复杂多变的岩溶地带，不同发育形态的岩溶对隧道施工和运营安全有较大的影响。织毕铁路杨家寨隧道岩溶强烈发育，施工过程中多次遇见不同规模溶洞，严重影响施工安全和施工进度。文章结合隧道施工过程揭示典型溶洞案例，分析总结了大型空溶洞和充填溶洞等不同性质岩溶处理措施及措施决策过程中需考虑的因素。岩溶整治过程中需因地制宜，结合岩溶形态、地质条件，充分考虑溶洞壁稳定性、岩溶水等影响因素，在保证结构受力安全的同时兼顾施工安全和施工进度等因素。文章对今后岩溶地区隧道施工具有重要的指导价值。
Abstract:
After water dissolution, the limestone formations will form complex karst areas, the karst with different development forms has a greater impact on the safety of the tunnel construction and operations. Yangjiazai tunnel of Zhibi railway has strong development karst, during the construction process, many different types of caves are encountered, the construction safety and construction progress are seriously affected. The paper analyzes and discusses big empty cave and filling cave disposition methods and the factors that need to be taken into account in the decision-making process by typical karst cases during tunnel construction process.In karst remediation, according to local conditions, combined with karst morphology, geological conditions, fully considering the stability of the cave wall, karst water and other factors, the safety of the structure shall be ensured while taking into account the construction safety and construction progress and other factors. The paper has great guiding value to the tunnel construction in the future karst area.
