摘要
本文以具体工程为背景,针对传统水泥土搅拌桩法在处理深厚软基中的缺陷,对预应力管桩在高速公路拼接工程中的应用进行了研究,介绍了刚性桩复合地基的设计方法。通过分析,采用预应力疏桩复合地基方案,处理效果明显,质量可靠,造价经济。
Based on the practical engineering and aim at overcoming the defects of the traditional cement mixing pile method on treating deep soft embankment, this paper researches the application of PTC in the connection engineering of expressway and presents the design method of the rigid pile compound embankment. The results of the analysis show that treatment present obvious effects with prestressed sparse pile scheme. The method features with reliable quality and low coat and could provide reference to related engineering.
