超大吨位单桩竖向抗压静载试验在高速公路工程中的应用分析

Analysis on the Application of Vertical Compressive Static Load Test of Super-Large Tonnage Single Pile in Highway Engineering

文章依托四川阿坝州高速公路工程中的大吨位单桩竖向抗压静载试验,结合现场大直径泥浆护壁冲孔灌注桩施工及山区岩土工程地质性质情况,试验得出大直径灌注桩极限抗压承载力,为山区高速公路工程中的工程设计人员提供设计参数依据,更好地服务我国山区高速公路工程建设。

Based on the vertical compressive static load test of large-tonnage single pile in Aba Prefecture Expressway Project in Sichuan,combined with the construction of large-diameter mud wall protection punched cast-in-place piles and the geological properties of rock and technical engineering in mountainous areas,the ultimate compressive bearing capacity of large-diameter cast-in-place piles is obtained.It provides design parameter basis for engineering designers in mountainous expressway engineering and better serves the construction of mountainous expressway projects in China.
