文章介绍了爆扩法处理液化地基的基本原理和试验段的工程实践,通过几种检测手段分析了采用爆扩法加固可液化地基的效果和地基处理施工现场的特征。实践证明,爆扩法在可液化地基处理中,具有成本低、速度快、处理效果好,不易受外界环境影响等优点,能适用高速公路液化地基处理,具有广泛的应用前景。 In this paper, the basic principles of blasting expansion method for liquefied groundwork and the engineering practice of the test section are introduced. The effect of using explosive expansion method to reinforce liquefiable foundation and the characteristics of foundation treatment and construction site are analyzed by several testing methods. Practice has proved that blasting expansion method in liquefiable foundation treatment has the advantages of low cost, high speed, good treatment effect, less susceptible to external environment and the like, and can be applied to express liquefied ground treatment of highway and has wide application prospect.
