坡纳屯～陇串村排涝渠(隧洞)修复工程地质条件分析评价

Analysis and evaluation of engineering geological conditions for Ponatun-Longchuan village drain canal(tunnel) repairing project

广西德保县隆桑镇坡纳屯~陇串村排涝渠(隧洞)修复工程由5段排涝明渠和5个排涝隧洞组成,工程区岩溶发育,岩溶塌陷、落水洞发育,水文地质条件复杂。分析了该工程的综合水文地质条件、地形地貌及岩土物理学特性,结合工程实际对排涝渠(隧洞)工程地质条件进行评价,针对出现的工程地质问题,提出相应的处理建议。

Located at Longsang Town, Debao county of Guangxi, the Ponatun-Longchuan village drain canal (tunnel) repairing project consists of five open canal sections and five tunnels. The project area is characterized by karst developed and collapse, developed sink-holes, complex hydrological and geological conditions. The author analyzed the comprehensive hydrological and geological conditions, topography, landform, geotechnical physics characteristics of the project, evaluated the engineering geological conditions, and put forward treatment suggestions for the geological problems.
