曲边界上任意分布荷载的数值计算

Numerical Calculation of the Equivalent Load on Bend Boundary by Arbitrary Distributing Force and Its Application

应用二次插值函数方法解决了曲边界受任意分布力作用的等效节点荷载数值计算问题,给出了基本算法,利用编写的程序,对一硐室边界曲线受法向分布压力作用做了平面问题数值计算模拟。

In this paper, the quadratic function is introduced to calculate the equivalent load of the nodes on bend boundary by arbitrary distributing force, and the corresponding computer program for analysis and numerical simulation software is developed. As the illustrative example, a round-pipe culvert by distributing pressure verticality inside is analysed, the distribution characteristic of main stress is given.
