摘要
根据试桩水平承载力的实测桩身弯矩,应用三次样条函数进行插值计算桩身的剪力,并对水平受荷单桩的内力计算编制了相应的Matlab程序。实例计算分析表明,该方法简洁直观,有效合理,精度可靠,可为桩基的设计计算提供依据和参考。
According to the pile shaft bending moment of a testing lateral pile, the pile shaft shearing force has been solved in cubic spline interpolation, and the Matlab procedure of solving the internal forces of the laterally loaded pile also has been compiled. This method is simple, validy, rationali with reliable accuracy, which are verified by an analysis example, and could provide basis and reference for designing a pile-foundation.
