摘要
郑万高铁湖北段处于鄂西山区,岩溶普遍发育。而在隐伏岩溶区,由于覆盖层的缘故,地质条件更加复杂,地质钻探难度更大。通过地勘监理,加强岩溶区桥址地质勘探质量控制,查明桩周及桩底的工程地质及水文地质条件,提高勘探质量,效果明显。结合郑万铁路岩溶桥址勘探实例,监理通过对岩溶区桥址的勘探准备、方案审查及作业现场的各环节质量控制,保证了桥梁基础的工程地质及水文地质信息的详实性、可靠性。通过对岩溶桥址钻探质量监理控制探讨,对提高类似工点的勘探质量,且为今后的监理工作,具有促进及借鉴意义。
The Hubei section of Zhengzhou-Wanzhou High-speed Railway is located in the mountainous area of western Hubei, and the karst is generally developed. In the hidden karst area, due to the overburden layer, the geological conditions are more complicated and the geological drilling is more difficult. Through geological exploration supervision, the geological exploration quality control of the bridge site in the karst area is strengthened, the engineering geological and hydrogeological conditions of the pile perimeter and the pile bottom are ascertained, and the exploration quality is improved, and the effect is obvious. Combined with the exploration example of the karst bridge site of Zhengzhou-Wanzhou High-speed Railway, the supervision ensures the fidelity and reliability of the engineering geological and hydrogeological information of the bridge foundation through the exploration preparation, scheme review and quality control of the various aspects of the operation site. Through the discussion on the quality supervision control of karst bridge site drilling, it is of promotion and reference significance for improving the exploration quality of similar work sites and for future supervision work.
