摘要:
为探究某隧道发生底鼓的原因，文章利用MIDAS 数值模拟软件模拟了隧道地质环境和施工工况。 结果表明：(1)高地应力和衬砌支护强度不足是导致隧道底鼓发生的主要原因，现场监测验证了数值模拟的 结果；(2)结合模拟结果、监测数据和工程经验，从设计处治和施工处治两个方面提出了治理隧道底鼓的有效 措施，后期监测数据表明以上两种处治措施有效的治理了隧道底鼓病害。本文研究成果可为类似的隧道底 鼓病害治理提供参考。
Abstract:
In order to identify the causes of the floor heaves of a tunnel，MIDAS numerical simulation software was used to simulate the geological environment and construction conditions of that tunnel. The results show that high crustal stress and insufficient lining support strength are the main causes of tunnel floor heaves，and the results of this numerical simulation were verified by field monitoring. According to the simulation results，monitoring data and engineering experience，this paper proposes effective measures to treat tunnel floor heaves from design and construction. The later monitoring data show that the above two treatment measures can effectively treat tunnel floor heaves. The research results of this paper can provide a reference for the treatment of similar tunnel floor heaves.
