摘要

摘要: 通过分析目前对海底隧道涌水量预测中使用的经验解析法和数值模拟法的局限性，采用模型试验的方法，基于相似理论，结合青岛胶州湾海底隧道水文地质和工程地质情况，以其右线的一个断面为模型，根据围岩渗透系数、黏聚力以及摩擦角配置了相似材料，并制作了海底隧道模型架和涌水量测量装置，同时在开挖过程中对位移、应力和渗压进行了监测。监测数据表明，本模型试验能较好的模拟海底隧道的实际开挖情况，试验所得涌水量与现场实测数据结果非常接近。通过解析解、数值解及试验观测值的对比表明，本试验在海底隧道涌水量预测方面具有较好的实用性，对指导防排水设计及施工实践有一定的参考价值。

Abstract: Through analyzing the main methods for forecasting water inflow in subsea tunnels, some disadvantages of the empirical analytical method and the numerical simulation method are obtained. Based on the theory of similarity, the method of laboratory modeling is adopted. Based on the situation of hydrology and engineering of Jiaozhouwan submarine tunnel in Tsingdao, a model is chosen from one of the sections of the right line of the tunnel. According to the infiltration coefficient, cohesion and friction angle of the wall rock, a kind of similar material is collocated. The submarine tunnel model equipment and the measuring devices for inflow water are made. In the process of tunneling, displacement, stress and osmotic pressure are measured. The measured results indicate that this laboratory model can simulate the real tunneling situation of submarine tunnels. The data of inflow from the tests is very close to the field data. Finally, from the comparison among the methods of empirical analysis, numerical simulation and laboratory modeling, it is shown that the proposed model can give a better application in the prediction of water inflow in submarine tunnels. The results are useful for guiding the design of waterproofing, drainage and construction.
