Abstract
Through site test in New Yingkou Station of Harbin-Dalian Passenger Dedicated Line, load sharing ratio of CFG pile and MIP pile in the composite foundation reinforced with CFG pile, MIP pile, cushion and reinforced concrete slab is analyzed. The results show that the stress ratio of CFG pile and MIP pile in the composite foundation increases with subgrade filling load. After filling, the stress ratio is basically unchanged. At the end of filling, the average stress ratio is 4.5. In addition, this composite foundation shows adaptive capacity关键词
