结合具体工程实例,介绍了路基防护桩在既有线扩能改造中的应用,通过对破裂角,破裂面位置的计算和桩身内力分析及其配筋计算,得出了一些有益的结论,以期促进路基防护桩在同类工程中的推广应用。
Combined with concrete engineering examples, this paper introduces the application of the roadbed protective pile in the expansion of existing line. Through the calculation of the rupture angle, the location of the rupture plane and the internal force analysis of the pile and the reinforcement calculation, some useful conclusions are drawn. Promote the promotion and application of roadbed protective pile in similar projects.
