摘　　要：以某煤矿新建桥梁工程为例,经稳定性分析和沉降观测,在不满足承载力、沉降量要求的情况下,拟采用CFG桩或水泥土搅拌桩进行地基处理;通过理论计算对比分析,得知CFG桩明显优于水泥土搅拌桩,不仅承载力高,沉降量小,且能节约成本,起到保护环境的作用.Taking the case of the new-made bridge engineering is a coal mine,it was concluded based on the stability analysis and settlement observation to treat the foundation by CFG piles or cement-soil mixing piles under the conditions that the bearing and settlement requirements were not met.The theoretical calculation and comparative analysis resulted in that the CFG pile was obvioushy superior to the cement-soil mixing pile with high bearing capacity and low settlement as well as cost reduced and environment protected.

关 键 词：采动区 CFG桩 地基加固 对比分析
