灰土挤密桩在湿陷性黄土地区公路工程软基处理中的应用

Application of Lime Soil Compaction Pile in Soft Foundation Treatment of Highway Engineering in Collapsible Loess Area

本文围绕灰土挤密桩施工技术及其在湿陷性黄土地区公路工程软基处理中的应用问题进行分析与探讨.首先, 对灰土挤密桩的基本概念及其应用特点进行简要分析, 然后结合某湿陷性黄土地区公路工程建设实例, 着重分析灰土挤密桩技术应用于软基处理中的施工参数及施工工艺, 以验证湿陷性黄土地区公路工程软土地基经灰土挤密桩处理后承载力及强度方面能否满足工程设计要求.

This paper analyzed and discussed the construction technology of lime soil compaction pile and its application in the soft foundation treatment of Highway Engineering in collapsible loess area. Firstly, it analyzed the basic concept and application characteristics of the lime soil compaction pile, and then combined with the construction example of a collapsible yellow land area. The construction parameters and construction technology of lime soil compaction pile used in soft foundation treatment were analyzed in order to verify whether the bearing capacity and strength of the soft soil foundation in the collapsible loess area could meet the engineering design requirements after the lime soil compaction pile was treated.
