| 摘 要： | 为了尽可能减少隧道长期大量排水带来的严重环境问题,高水位地区的深埋山岭隧道应采取"以堵为主,限量排放"即"堵水限排"的防排水设计准则.但在堵水限排情况下围岩的力学特性如何?是当前隧道衬砌结构设计急需解决的关键问题之一.首次建立了山岭隧道堵水限排情况下围岩力学特性分析的解析模型并进行了理论推导,分析了不同排水工况下围岩力学特性的变化并绘制了相应的围岩特征曲线,为堵水限排衬砌结构设计提供了理论依据.

| Abstract: | To cut down the serious environmental problems caused by tunnel drainage with no control as possible, the waterproof criteria of “block off ground water and limiting discharge” that is controlled drainage should be adopted in mountain tunnels with high water level. But how is the mechanical character of the surrounding rock with controlled drainage? It is a key and urgent problem in tunnel design now. An analytical model is established for the first time to analyze the mechanical character of the surrounding rock with controlled drainage; and a series of equations are deduced. The variation of the mechanical character of the surrounding rock with controlled drainage is analyzed; and the corresponding ground reaction curves are drawn; this is a theory base for tunnel design with controlled drainage. |
