| Abstract: | There are a lot of treatment methods of karst tunnel at present,but their costs are usually higher. For this reason,the cost must be rationally determined and effectively controlled,in order that the goal of feasible technology with rational economy can be achieved in the design scheme of karst tunnel treatment. Taking actual project as example,this paper carried out technical economy comparison among the three treatment schemes for the same karst tunnel,including the scheme of pile foundation with joists, the scheme of chemical churning piles,and the scheme of micro piles. Finally,this paper recommended a good treatment scheme which was feasible in technology and rational in economy. |
