高速公路路基板桩施工技术研究

Study on Construction Technology of Highway Subgrade Sheet Pile

为研究高速公路路基板桩施工技术,结合实际工程,针对路基高边坡特性,提出一种板桩防护技术,即抗滑桩加挡土板设计,重点对抗滑桩和挡土板施工技术要点进行研究,并提出防护质量检测标准。研究结果表明,采用板桩施工技术可有效提高路基的整体稳定性和结构强度,延长路基防护寿命。

In order to study the construction technology of sheet pile in expressway subgrade, combined with the actual project, according to the characteristics of high slope of subgrade, a sheet pile protection technology is proposed, that is, anti-slide pile and retaining board design, the key points of construction technology of anti-slide pile and retaining board are studied, and the protection quality detection standard is proposed. The results show that sheet pile construction technology can effectively improve the overall stability and structural strength of roadbed and prolong the protection life of roadbed.
