爆炸排水固结实验研究的加速度测量

软土地基加固技术是地基工程中一个重要问题，在大量工程实践的基础上，作者采用爆炸法研究了淤泥的排水固结。由于爆炸引起地基的振动加速度与排水关系密切，因此通过实验测量了离爆源近区的加速度，得到加速度随爆炸距离的变化规律；观测分析了爆炸振动过程的加速度波形；通过测定爆炸前后淤泥的土工指标，表明爆炸后短时期内淤泥含水量有所变化

SYSTEMATIC MEASUREMENT ON ACCELERATION IN BLASTING FOR SQUEEZING OUT WATER FROM MUD

The consolidation of soft foundation is very important in engineering constructionA new method for squeezing out water from silt and consolidating the soft foundation by blasting was proposed in this paperSystematic measurements on acceleration of silt in blasting were carried outThe tests indicate that the mechanical indexes of the mud are raised after blasting and the relationship between the acceleration of silt in blasting and the distance of blasting was obtainedBased on the experimental results,the mechanism of consolidation of soft foundation of blasting was analyzed
