Abstract
In order to eliminate the errors caused by human subjective factors in the process of determining the weight of influencing factors of dynamic compaction construction control index.Taking tamping subsidence,effective reinforcement depth and tamping distance as targets,the factors such as soil parameters,tamping shape and construction technology as behavior factors are selected,and the correlation between them is established by grey correlation theory.On this basis,a mechanical-empirical model of control index is established by means of multiple regres-sion analysis.The results show that;In terms of tamping subsidence,effective reinforcement depth and tamping distance,tamping energy,soil weight and tamping bottom area should be the main controlling factors.The established mechanical-empirical model has high accuracy,R2is above 0.9,which can provide theoretical reference for the selection of construction technology,soil parameters and construction equipment in the early stage of dynamic compaction construction.关键词
