摘要
文章以弹性地基反力法为基础,结合支盘桩的桩身挠曲微分方程,利用有限差分法得出了支盘桩桩身变形的差分方程。通过数值模拟软件得出了相应的拟合曲线,分析得出了支盘桩水平承载力的初步设计理论。
In this paper, based on finite difference equation and elastic subgrade reaction method, the deformation differential equation of squeezed branch piles is concluded with the branch pile＇s own deflection differential equations.Obtained by numerical simulation software corresponding to curve fitting,the analysis reveals that the preliminary design theory of branch pile＇s horizontal bearing capacity.
