摘要

It is very difficult to treat divergent settlement between bridge and embankment lying on soft foundation. On Certain Test Portion of Jingzhu Freeway, treated soft foundation between bridge and embankment was adopted rubble pile, jet pile, short and dense jet pile, and treating result attain to require. At the same time, indoor fit ratio test, large scale unconfmed compressive strength test of engineering pile, site loading test of each treating method, settlement observation of each treating area were carried out, and many experiment data was earned. In this text, experiment result was researched by contrastive analysis.
