摘　　要：研究了爆破挤淤法在陆上应用的机理;基于土力学与爆炸力学的基本理论,得出了能反映布药参数与淤泥参数的用药量公式;结合现场试验,给出了陆上爆破挤淤法的施工工艺和检测方法,并就试验过程中出现的现象进行分析;检测结果表明,爆破挤淤技术可以满足特殊条件下软基处理要求。The blasting toe-shooting method is a new technique for soft foundation treatment. The mechanism of blasting toe-shooting method used in mountainous area is studied. Based on the basic theory of soil mechanics and explosive mechanics, the formula of charge weights in relation to the parameters of the charge and the soil is given. Furthermore, the construction techniques and testing method for the blasting toe-shooting method are obtained according to the analytical results and the observed data. The final test results show that the blasting toe-shooting method can satisfy the requirements of the bearing capacity and deformation of embankment foundation.
