摘要
山岭隧道采用半包防水设计时,常常出现排水不畅、基底承载力下降、不均匀沉降、翻浆冒泥等病害。因此以某重载铁路隧道为例,对比了新旧防排水设计方案,并通过软件模拟分析,进一步验证了改进方案切实可行,为类似工程项目的设计和施工提供了参考和借鉴。
When mountain tunnels are designed by half ladle drainage,diseases such as poor drainage,decrease of base bearing capacity,uneven settlement,mud pumping and other diseases often appear.Taking a heavy haul railway tunnel as an example,its’new waterproof and drainage design scheme is compared with the old one.The improvement is tested to be feasible by software simulation analysis and provide reference for the design and construc-tion of similar projects.
