摘要
Abstract
Based on a highway project in saturated loess area under construction,the change rule of pile-soil stress ratio of granular pile composite foundation is analyzed and calculated through on-site measurement.The results show that:the size of pile-soil stress ratio is related to the strength of the soil between the piles,the greater the strength of the soil between the piles,the smaller the pile-soil stress ratio;embankment filling process stress sharing ratio is affected by the filling time and filling speed;granular pile composite foundation on saturated loess area soft ground treatment is reasonable and effective,it is recommended that the pile-soil stress ratio is 1.80.关键词
