- 摘要:
- 五指山隧址区有10种岩溶形态,在隧址区地质调查基础上,分析了五指山地区岩溶发育的演化历史.采用径流模数法、年降雨有效渗入时间系数法及地下水动力系数法对各区段隧道涌水进行了计算,并对隧道贯通前后涌水动态变化进行了分析.五指山隧道主要涌水位置有5处,其中进口段的“8.6”断层突水和出口段的膏溶角砾岩突水,突水量大,给隧道施工和隧址区环境带来严重影响.
- Abstract:
- There are ten types of Karstic Features in Wuzhi mountain tunnel.The evolvement of karst in Wuzhi mountain was analyzed based on geology investigation.Water gushing in each sections of the tunnel was predicted by using methods of runoff modulus,effective infiltration of rainfall at different time intervals annually and dynamics of groundwater.And dynamic changes of water gushing were also analyzed in the tunnel before and after its completion.Water gushing in Wuzhi mountain tunnel have five sections.And the large gushing yields from the fault ‘8.6’ at the entrance section and from the Gypsum breccia at the exit section cause serious effects on the construction and environment in the tunnel.
