    南川至道真高速三泉隧道下穿岩溶暗河涌水点特征

    FEATURES OF WATER BURST WHEN BUILD NANCHUAN TO DAOZHEN SANQUAN TUNNEL UNDER THE UNDERGROUND RIVER

    • 摘要: 由于岩溶发育的复杂性,岩溶区隧道建设涌水预测难度大。本文选取以暗河下穿越的三泉隧道为研究对象,通过调查、长观等手段,总结暗河影响带涌水点的分布、类型、连通性以及受降雨影响特征。分析得出,隧道涌水点集中分在里程K7+047~K7+0130范围内;涌水量在岩层倾向方向侧涌水段增大;隧道涌水主要位于暗河来水方向侧;涌水点之间具有相对连通性;降雨影响下,溶隙涌水点水量变化幅度小,岩溶管道涌水点水量变化幅度大。

       

      Abstract: On account of the complexity of the karst growth, it is difficult to predict water burst during tunnel construction. By methods of investigation and observation, this article take the Sanquan tunnel for example, to find the distribution, types, connectivity, and response after rainfall of water burst. The tunnel water burst range on K7+047 to K7+0130. The water burst is increased in the direction of rock tendency. Water burst mainly appear in the direction of underground river origin. Water burst points are connected. Under the influence of rainfall, rock fracture water burst vary in small amplitude, and karst pipe water burst vary sharply.
