摘　　要：黄土地区机场建设工程存在湿陷性软土地基问题,本文以太原机场机坪扩容工程为例,采用“换填垫层配合冲击碾压”的方法处理场区软土地基,通过分析地基承载力、固体体积率、反应模量等数据来控制地基处理的相关施工参数。评估结果表明,采用换填垫层法可以有效治理软土地基的湿陷性。In this paper,taking the expansion project of Taiyuan Airport Apron as an example,the soft soil foundation in the field area is treated by the method of"replacement cushion and impact rolling",the related construction parameters of foundation treatment are controlled by analyzing the data of foundation bearing capacity,solid volume ratio and reaction modulus.The evaluation results show that the replacement cushion method can effectively control the collapsibility of soft soil foundation.
