【摘要】 在南吕梁山隧道工程地质选线中,如何绕避采空区,优化穿煤段,并确保工程建设不破坏龙子祠泉域水环境,保证临汾市70万居民用水是关键问题。在可行性研究阶段,通过对水文与工程地质综合勘察,查明测区的煤层与岩溶水环境等地质条件,创造性地提出隧道从煤层与采空区以下、龙子祠泉域饱和水位以上的地层中通过。施工实践证明,隧道工程地勘资料是准确的,地质选线是科学合理的。更多还原

【Abstract】 In the engineering geological location of South Lvliangshan tunnel,issues,such as how to avoid the goaf areas,how to optimize the coal-crossing section,how to guarantee that the water environment of Longzici spring is not damaged and how to guarantee the water supply for the 700 000 citizens in Linfen city,are essential.It is proposed,on basis of hydrogeological surveys and engineering geological surveys,that the tunnel should pass through the strata below the coal seams and goaf areas,but above the saturated water level of Longzici spring.The construction of the tunnel shows that the engineering geological location of the tunnel is rational and correct.更多还原
