横向受力下埋入超长桩的有限差分法数值计算

Numerical calcuation of finite-difference for buried-overlength pile under lateral loading

为了探讨埋入超长桩在横向受力下的有限差分法数值计算,基于m法微分方程,利用有限差分法将其微分方程差分离散化,编制了MATLAB计算程序进行相应的数值计算,并结合试桩的水平静载荷试验,进行了性状分析。

To investigate the numerical calcuation of finite-difference for buried-overlength pile under lateral loading, based on differential equation of m-method, the differential equation is differenced and dispersed with finite-difference method. And programme caleultive program of MATLAB is worked out in order to make a numerical calcuation, what＇s more, combine the level dead-load test of trial-piles to analyse the its capability.
