桩间爆炸处理软基的模型分析及试验研究

ANALYSIS OF MODEL AND EXPERIMENT ON HANDLING SOFT FOUNDATION BETWEEN PILES

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。

By analysis of model experiment in lab and site,it is deeply and carefully studied that how to handle soft foundation between piles by blasting,which has strong background of engineeringThe displacement,state of strain,stone-pile and width of stone-pile after blasting are measured,and experiment data are analyzedThe method to handle soft foundation between piles by blasting is reliable,safe and easy to operate,and with better strengthening effectAt the same time,the blasting parameters are recommended for application in engineering projects in this paper
