地基承载力不足对公路隧道的影响分析

Analysis of the Influence of Insufficient Foundation Bearing Capacity on Highway Tunnels

文章针对广西公路隧道隧址区地质复杂问题及隧道病害问题越来越多的现象,采取数值模拟分析的方式分析了地基承载力不足、基底发生沉降时公路隧道的力学特点,并结合数值分析结果及工程实践经验,探讨了基底沉降对公路隧道的影响,并提出了针对性的对策。

In view of the increasing geological complexity of Guangxi highway tunnel sites and the increasing number of tunnel disease problems,this article analyzes the mechanical characteristics of highway tunnels with insufficient bearing capacity and foundation bottom settlement by numerical simulation,then,combining the numerical analysis results and engineering practice experience,it discusses the influence of foundation bottom settlement on highway tunnels,and proposes the targeted countermeasures.
