摘要
目前,我国公路隧道普遍存在渗漏现象,寒区隧道还会由渗漏进一步引发冻害,它们严重影响了公路隧道的正常运营。针对这一现状,通过对金丽温高速公路某连拱隧道渗漏水状况进行调查,分析了隧道渗漏水的特点及其原因,用有限元模拟计算了隧道开挖后地下水渗流情况,进而提出了隧道渗漏的若干预防措施和治理建议。
The characteristics and reasons of leakage in tunnels are analyzed through investigating the leakage conditions in a multi arched tunnel of jinliwen expressway. The seepage conditions of ground water after tunnel excavation are calculated by FEM simulation and then some precautionary measures and treatment suggestions on tunnel leakage are put forward.
