天坛山隧道渗漏水病害机理分析及防治技术

结合山西省晋阳高速天坛山隧道工程实例,在了解隧道渗漏水病害概况的基础上,分析了隧道渗漏水病害机理,指出其渗漏水病害发生的主要原因在于其地质、设计施工、地表水及地下水等因素,采用"重新布设防排水设施+25 cm的钢筋混凝土衬砌"的防治方案取得了良好的效果。

Study on the seepage mechanism and the prevention from seepage disease of Tiantanshan tunnel

In this paper, we select the Shanxi Jin-Yang highway Tiantanshan tunnel as the project example, based on the general situation of wa- ter leakage, analyze the disease mechanism. We can conclude that the main reason of water leakage are geology, design, construction, surface water and ground water. For controlling the disease, we rearrange the fortification drainage, and pour the 25 cm reinforced concrete. It has an ob- vious controlling effect on the water leakage.
