摘要
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 ,以及沉桩对原路的影响。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 。
For traditional methods of ground improvement such as co ncrete soil pile have shortages in improving the deep soft soil ground in connec tion section expressways engineering, the application of the prestressed pipe pi le is studied in this paper, and the design method of the rigid pile complex grounds is introduced. Analysis indicate that the method has obvious effects on soft soil ground improvement, and more economical than concr ete soil pile. It can offer reference for the related engineering.\;
