石灰岩溶隧道施工

CONSTRUCTING TUNNELS WITH SILUABLE CALCAREOUSROCKS

石灰岩溶地质复杂，隧道施工中常见涌水突泥，地表坍陷，给施工与运营造成极大困难，整治也十分艰难，本文介绍多年来岩溶隧道施工的经验和教训，提出施工中的主要问题和应采取的对策。

As constructing the tunnels with soluable calcareous rocks whose geological con-ditions are complex, the outflow,mud-flow and surface collapse are usually occurred,caus-ing the construction of tunnels and later thc maintenance in traffic extremely difficult andhardly to be brought under control.The experiences and wrongdoings in constructing suchtunnels for so many years are introduced.This paper points out also the principal problemsin constructing such tunnels and suggests the countermeasures that should be adopted.
