澜阿公路那勒隧道炭质页岩段变形原因及治理研究
|
摘要
澜阿公路那勒隧道炭质页岩段富水、自稳能力差、变形大,对隧道施工造成巨大的困难。通过对实际地质情况进行分析研究,找出隧道出现一系列病害的原因,从改善围岩、调整支护参数、优化开挖防护施工方法等方面制定了针对性的综合处治措施,取得良好的效果,为类似工程的设计、处治提供了参考。
A LAN highway tunnel segment Nala carbonaceous shale and water poor stability, large deformation, caus-ing great difficulties for tunnel construction. Based on the actual geological condition analysis, find out the reasonsfor a series of diseases of the tunnel, improve the surrounding rock, from the adjustment of support optimization of ex-cavation protection construction method and support parameters for comprehensive treatment measures, and achievedgood results, which provides a reference for the similar project design, treatment.
