摘要
随着交通事业的高速发展,公路桥梁负荷的加重,桥梁对桩基础的要求也日益提高。面对出现的各种新问题,该文提出利用有限元法来分析桩土的相互作用,并利用Ansys软件,结合工程实例对桩基进行模拟分析。通过分析,得出了桩体沿纵深方向Z方向的位移等值线图,沿X方向位移等值线图、沿Y方向位移等值线图、荷载-沉降曲线以及桩侧摩阻力图。结合理论分析得出大直径灌注桩在竖向荷载作用下的工作性状。
With the high-speed development of traffic facilities and the sharpening of the highway bridge load,the requirements of the bridge for the pile foundation are also enhanced day by day. Facing various new problems,the article puts forward to utilize the finite element method for analyzing the interaction of pile and soil.And utilizing ANSYS software and combined with the practical engineering example,the article simulates and analyzes the pile foundation.After the analysis,the article gives the displacement isoline chart of Z direction along the depth direction,the displacement isoline chart along X direction,the displacement isoline chart along Y direction,load-settlement curve and pile side frictional resistance chart.Combined with the theoretical analysis,the article gives the working status of the large-diameter cast-in-place pile under the vertical loading action.
