岩溶地区路基注浆加固施工技术

Construction Technique of Roadbed by Injection Grouting Consolidation in Karst Region

岩溶是水对地表及地下可溶性岩石的化学溶解和机械破坏剥蚀过程中所产生的一种不良地质现象,它对铁路路基存在极其严重的危害作用,也对铁路行车安全构成隐患.通过对岩溶地区铁路路基注浆加固施工技术以及施工控制检测的基本介绍,为类似工程提供了可借鉴的实践经验.

Karst is an unfavorable geological condition, which brings in the process of water's chemical dissolution and mechanical erosion to solubility rocks of the earth's surface and underground. It will bring very serious destroy to roadbed of railway, and make hidden danger to railway operation as well. In this paper, the general situation of construction technique of roadbed by injection grouting and consolidation and quality control in karst region is introduced in brief, it provides a good example for the similar projects.
