通过模型分析、模型实验及现场实验对爆炸法处理桩间软基这一具有较强工程背景的课题进行了深入的分析及实验研究，测量了爆炸载荷作用下桩的变形、受力状态及抛石体爆后落底宽度等，并对大量实验数据进行分析处理。认为采用堤下爆破法处理桩间软基是一种安全、可靠、加固效果好且施工工艺简单易行的新方法。同时本文还给出了供工程应用的推荐爆破参数 Through the analysis of the model, the model experiment and the on-site experiment, the problem of explosive engineering soft foundation treatment is studied in depth with the engineering background. The deformation, stress state, The bottom of the body after blasting bottom width, and a large number of experimental data analysis and processing. It is considered that the treatment of soft ground between piles by embankment blasting is a new method which is safe, reliable, has good reinforcement effect and simple construction process. At the same time, this paper also gives the recommended blasting parameters for engineering application
