摘要
通过现场实验和数值模拟分析了软土地基在爆炸荷载作用下长期和瞬间的变形特性,分析了影响爆炸效果的主要因素和条形药包爆炸后冲击波的显著影响范围,并讨论了爆炸固结法处理软土地基的作用机理,表明该法具有加快固结速度的特点,有利于提高施工速度,缩短工期。
The long-term and transient deformation characteristics of soft soil ground under explosive loading are analyzed through the field test and numerical simulation. The main factors affecting explosion results and the remarkably impact range in the soil after explosion are investigated. Mechanism of improving soft ground by explosion is discussed. The results show that this method can accelerate consolidation speed, improve the construction speed and shorten the time limit for a project.
