摘要:
近年来，我国岩溶地区隧道衬砌渗漏水病害频发，尤其是由于隧底高水压导致仰拱上鼓、轨道变形的现象屡有发生，造成了严重的经济损失和负面影响。为解决隧底高水压问题，本文针对性提出了4种防排水方案，通过数值模拟研究了不同方案的衬砌水压分布规律及排水泄压效果，确定了可降低隧底高水压的最佳防排水方案。研究结论可为高压富水地区的岩溶隧道防排水设计提供参考。
Abstract:
In recent years, water leakage of tunnel lining in karst areas, especially invert bulge and track deformation due to the high water pressure at the tunnel bottom, occurred frequently in China, which caused serious economic losses and negative effects. In order to solve the problem of high water pressure at the tunnel bottom, 4 waterproofing and drainage schemes are proposed in this paper. The distribution laws of the water pressure acting on the lining and the drainage and pressure relief effects of these schemes are studied through numerical simulation, and the best waterproofing and drainage scheme for reducing the high water pressure at the tunnel bottom is determined. The conclusions of the research can provide references for the design of the waterproofing and drainage system for karst tunnels in high-pressure and water-rich areas.
