摘要
The distribution area of Cambrian strata the longest one in Dawushan tunnel construction. The engineering geological problems are prominent, especially the frequent development of fault and fissure, high level of underground water, welling, sand boil, collapse, etc. In the early period and other different stage of the construction, we have carried out different prevention measures and suitable processing building, which have ensured the construction progress and quality.
