隧道坍塌是隧道工程最为常见的地质灾害之一。本研究分析了广佛肇高速公路黎壁山隧道的自然条件、工程地质及环境地质。从地质角度探讨了隧道坍塌形成的原因,提出了“稳固后方、加固前方、上堵下排侧引、探明前方”相结合的坍塌处治方案。
Tunnel collapse is one of the most common geological disasters in tunnel engineering. This study analyzed the natural conditions, engineering geology and environmental geology of the Lipeishan Tunnel of Guangfo-Zhaozhao Expressway. The reason of tunnel collapse was discussed from the geological point of view, and the collapse treatment scheme of combining “solid front, reinforced front, upper block and lower side guide, proven front” was proposed.
