摘要
以大广北高速公路(麻城至浠水段)实体工程为依托,介绍了振动沉管挤密碎石桩(碎石桩)和水泥深层搅拌桩(粉喷桩)的施工工艺,分析了采用不同方式处治后复合地基的实测地表沉降数据,对比了在软土地基条件下碎石桩与粉喷桩的加固效果,并确定了其适用范围。
In the foundation of the project of Daqing-Guangzhou North expressway（Macheng-Xishui section）,this paper introduced the construction technology of vibration gravel compaction pile（gravel pile）and cement deep mixing pile（powder sprayed piles）,.The reinforcement effect of gravel pile and powder sprayed pile were compared based on the settlement data of ground surface after treatment in the condition of soft soil,which can be used to evaluate their application scope.
