钻爆法水下隧道地下水治理一般采用注浆环、喷射混凝土衬砌（初衬）、混凝土衬砌等方式进行。透水注浆环和喷浆衬砌对渗流场有重要影响。但目前发表的相关成果的研究模型都是针对均质、各向同性的单层无衬砌隧道，忽略了隧道注浆圈和初次衬砌的重要影响。如果直接采用相关文献的结论来指导隧道设计，可能会出现较大的误差。因此，本文在前人研究的基础上，对隧道渗流研究模型进行了扩展，将隧道注浆环和初衬砌纳入研究模型中。研究模型更符合实际工况。基于镜像法原理，将无限含水层排水隧道渗流场与无限含水层给水隧道渗流场叠加，得到半无限含水层灌浆喷混凝土衬砌水下隧道渗流场解析解，并通过数值分析和试验进一步验证。此外，利用偏微分分析讨论了注浆环和初衬砌参数对渗流场的影响。结果表明,降低注浆环及初衬砌渗透系数或增加注浆环及初衬砌厚度可显着缓解隧道渗流,但注浆环及初衬砌水压会增大。
Groundwater control in underwater tunnels by drilling and blasting method is generally carried out by grouting ring, shotcrete lining (primary lining), and concrete lining. The permeable grouting ring and shotcrete lining have an important impact on seepage field. However, the currently published research models of related results are for homogeneous and isotropic single-layer unlined tunnels, ignoring the important effects of tunnel grouting circles and primary lining. If the conclusions of the relevant literature are directly used to guide the tunnel design, large errors may occur. Therefore, on the basis of previous studies, this article extends the tunnel seepage research model and incorporates the tunnel grouting ring and primary lining into the research model. The research model is more in line with actual working conditions. Based on the principle of mirror method, the seepage field of a drainage tunnel in an infinite aquifer is superposed with that of a water supply tunnel in an infinite aquifer, and the analytical solution to the seepage field of an grouted and shotcrete lined underwater tunnel in a semi-infinite aquifer is obtained, which is further verified by numerical analysis and experiment. In addition, the influence of grouting ring and primary lining parameters on seepage field is discussed by using partial differential analysis. The results show that the seepage flow of tunnel can be significantly alleviated by either reducing the permeability coefficient of grouting ring and primary lining or increasing the thickness of grouting ring and primary lining, but the water pressure of grouting ring and primary lining will increase.
