Abstract The geological condition，basic physico-mechanical properties and treating measurements of K35+930～K36+410 section of Yinjiazhuang—Zhongchuan Airport highway are described. The main procedures of field loading test，its technological points and the stability standard are introduced. The research is based on the engineering practice of twenty two chemical injection churning piles，four chemical churning piles，four blocks of ground between chemical churning piles and six blocks of composite ground with three piles in two sections. The test results are analysized and evaluated.

Key words： soft ground chemical injection churning pile chemical churning pile composite foundation test evaluation
