Journal: Underground Water
Keyword: the hydro-geological condition; inflow yield; high altitude; to drive up row and section calculation;
Abstract: The Xiaokazi Tunnel is a portable road to connect Jiulong and Shimian Counties.It is green protection to con-nectS215 andS211.Thealtitudeisabove4000mbetweenJiulongandShimian.AtJiulongcountysurroundingsistheplat-eau dale and upland region and the terrain is undulating seriously.For the growth of the poor geology and special drape structure from Jiulong to the surroundings,the damage caused by ice and snow occur almost every year and influence the line for a long time.The other geological disasters are frequent outbreaks which causing traffic accidents occur frequently,as a constraint to the development of Jiulong County.And thus an urgent requirement on line transformation,it proposed to build a Xiaoka tunnel to connect Jiulong County and Shimian counties,so it calls the highway reconstruction project.
