Lime-soil pile has been treated to high fill loess foundation in Yan'an New Area,4 groups were designed in the test site.Light dynamic penetration test and load test had completed. Change laws of N10 and dry density γdwhich are of single pile,two piles and three piles test points were analyzed. Compression coefficient a1-2 and settlement characteristic under different lime-soil pile parameters were obtained. The test results show that the effective reinforcement of the single pile is 2. 0 d,and of two piles and three piles is 2. 5 d ~3. 0 d.
