摘要
某公路双联拱隧道,在验收之前二次衬砌产生裂缝病害状况,本文主要通过现场病害状况调查,并分析了病害的成因,通过温度裂缝理论建立有限元模型对裂缝的形成进行数值分析,最后进行温度裂缝的控制及处治措施,并提出了相应的治理意见。
A tunnel of highway of Shanxi is a double - arch tunnel. When the principal part of the project was completed, some disasters occurred. The disasters included the cracks and leakage of the secondary lining. The paper analyses the cause of formation of the disasters, simulates the formation of the cracks with FEM program and presents some measures of treatment.
