| 摘 要： | 随着我国隧道通车里程与运营时间的不断增长，越来越多的隧道进入病害高发期，地下水是导致隧道病害最为严重的因素之一，容易诱发衬砌发生渗漏水等病害，为研究隧道衬砌渗漏水病害发生机制，研制了三维地质力学模型试验系统，开展了不同埋深条件下隧道衬砌渗漏水病害模型试验研究。该系统由可拓展模型试验台架、地应力模拟加载装置、地下水模拟加载装置、多场信息实时监测装置和衬砌渗漏水实时量测装置等组成，利用油压千斤顶和多功能加载水泵，采用分级加载方式可对隧道不同埋深进行模拟。将该系统应用于隧道衬砌渗漏水病害模型试验研究，通过对渗漏水量、渗压和位移等信息进行分析，揭示了不同埋深条件下穿越交叉断层隧道衬砌渗漏水病害的演化规律，并对堵排结合治理方案进行了初步研究，验证了排水对降低衬砌渗漏水量的积极作用，试验结果与运营期开元隧道衬砌渗漏水病害工程实例吻合良好，证明该系统稳定可靠，其研究方法及结果可为相关工程提供一定的参考。

| Abstract: | With the increasing traffic mileage and operation time of tunnels in China, more and more tunnels have entered a period of high disease incidence. Groundwater is one of the most important factors easily causing the water leakage in tunnel lining. In this paper, a three-dimensional geomechanical model test system was developed to investigate the mechanism of the water leakage disease in tunnel lining with different buried depths. The model test system was composed of an extendable model bench, a loading system of ground stress and hydraulic pressure, a multivariate information real-time monitoring system and water leakage real-time measuring device. Using oil jacks and multi-function water pump, the system can simulate the behaviors of tunnels at different buried depths by the stepwise loading method. This model test system was applied to simulate the water leakage in tunnel lining under different buried depths. The evolution law of seepage disease in the tunnel lining crossing cross-fault tunnel under different burial depths was revealed through the analysis of seepage quantity, the seepage pressure and displacement information. At the same time, a preliminarily study was conducted on the combined treatment of blocking and drainage. The positive effect of drainage on reducing the lining seepage quantity was verified. The test results are in good agreement with the results from Kaiyuan tunnel lining seepage disease in operation period. This study proves that the system is stable and reliable, and the research methods and results can provide useful references for related projects. |
