摘要
在建宜万铁路箐口车站路基岩溶极其发育,地质条件复杂,施工对岩溶路基制定了"先探后灌、探灌结合"的压力注浆施工原则,根据勘探揭示的不同地质情况制定了科学合理的注浆加固方案和加固效果的现场检验方法,成功地解决了岩溶路基施工技术难题,满足了路基强度、质量要求。
The karst of the roadbed in Qingkou Station of Yichang - Wanzhou Railway grows extremely, and the geological condition is complex. In the construction the injection principle of ＂first searches, and then injection＂ is formulated. According to the different geological situations, the scientific and reasonable injection reinforcement plan＇and the in-situ inspection procedure for the reinforcement effect are made out. The difficult problems in the construction for the karst roadbed are solved successfully to satisfy the intensity and quality requirement of the roadbed.
