摘要
南钦防改扩建工程拼接加宽软基深度大于2.5m的路段,采用素混凝土桩处理方式,效果良好。文章结合南钦防改扩建工程实例,介绍了素混凝土桩的设计方案,分析了素混凝土桩施工过程质量控制要点,为今后其它高等级公路拼接加宽软基处理提供借鉴和依据。
Nanni ng-Qinzhou- Fangcheng reconstruction and expansion project requires the splicing widening for the soft foundation section over 2. 5 m deep,and the plain concrete pile treatment method has good result.Combining the example of Nanning-Qinzhou-Fangcheng reconstruction and expansion project,this article introduced the design plan of plain concrete piles,and analyzed the key points of quality control during the construction of plain concrete piles,which can provide reference and basis for the future splicing widening treatment of soft foundations in other high-grade highways.
