将任意线型、变曲率、变厚度、弹性支承拱式体系分成ｎ个单元，利用三角形荷载处理任意的分布荷载，利用曲线模拟的方法处理任意的拱轴，采用文克尔假设及伏格特假设处理基础，对每个单元用经典理论推导出计算公式，对公式中的积分式用Ｓｉｍｐｓｏｎ积分数值化，然后采用递推理论、传递矩阵及迭加原理将各单元间的相互作用进行组合。通过算例，本文的理论方法及程序正确，为拱型体系提供了一种通用而快速的计算方法
Arbitrary linear, variable curvature, variable thickness, elastic support arch system is divided into n units, triangular loads are used to process arbitrary distributed loads, and any arch shafts are processed by means of curve simulation, using the Winckel hypothesis and Vogt. Assuming the processing basis, a formula is deduced for each unit using classical theory. The integral formula in the formula is numerically scaled by Simpson integral. Then the interaction between the elements is combined using the recursion theory, transfer matrix and superposition principle. Through examples, the theoretical methods and procedures in this paper are correct, providing a universal and fast calculation method for the arch system.
