某铁路隧道塌方原因分析与处治方案研究

Study on Causes Analysis and Treatment Scheme for Collapse of A Railway Tunnel

结合某隧道工程塌方,从工程与水文地质条件、设计以及施工等方面分析其发生塌方的原因,并进行相应的处治方案比选。结果表明:采用超前小导管注浆并结合塌腔回灌混凝土的塌方处治方案安全可行、经济合理。

Taking the collapse in a tunnel engineering as an example, the causes were analyzed from the aspects of engineering, hydrogeological conditions, design and construction, and then the corresponded treatment scheme was established. The result shows that the scheme used is feasible and economic and could be referred in collapse treatment to the similar tunnel engineering.
