摘要:

研究了以保护隧道洞口边仰坡植被环境为目的,提出无仰坡洞口开挖方法,并结合重庆洪—酉高速公路大董岭隧道工程,对前置式洞口工法与隧道洞口传统施工方法进行了数值模拟分析,通过对两种施工方法在洞口开挖后无锚喷支护情况下所产生的位移、应力与稳定性等的综合比较,为前置式洞口工法在环保及洞口仰坡稳定方面的优越性提供了理论依据。

Abstract:

The excavation without front slope at the tunnel entrance is presented in this paper. The traditional method and advanced entrance construction method (AECM) are conpared with nurmerical simulations in the construction of Dadongling highway tunnel which located on HongYou highway in Chongqing. According to the comparison of displacement, stress and stability in the case of without anchoring and shotcreting, the theoretical support of AECM is given.

Key words:  , highway tunnel AECM traditional method numerical simulation comparison
