Abstract：The blasting toe-shooting method is a new technique for soft foundation treatment in mountainous area. Based on the theory of soil mechanics and explosive mechanics，the mechanism of blasting toe-shooting method used in mountainous area is studied，and the formulae of charge weight about relations between the parameters of charge and soft clay are presented. Furthermore，the construction techniques of blasting toe-shooting method and test means of foundation after being improved are obtained according to analysis of experience and mechanism. The achieved results show that blasting toe-shooting method can satisfy the requirements of the bearing capacity and deformation of embankment foundation in mountainous area.
