摘　　要：以深厚软土地区某铁路工程为例,对搅拌桩、管桩及两者结合的地基加固方案进行分析比较,介绍了多桩型复合地基加固在深厚软土地区的应用。其复合地基承载能力可达250 kPa,而且工后沉降满足设计要求。Taking a railway project in deep soft soil regions as an example, the paper analyzed and compared the schemes of foundation reinforced by mixing piles, tubular piles or the combination of both respectively, and then introduced the application of multi-type pile composite foundation reinforcement in deep soft soil regions. The bearing capacity of the composite foundation thereof may reach 250 kPa and the post-construction settlement meet the design requirement.
