一、概述1 引言用角变位移法解连拱问题的思路最为简单,但在孔数较多时解大型线性方程组的工作量很大。为此不少学者提出了各种简化近似方法。它们或者减少计算的孔数,或者设法减少方程组的元数。然而在桥墩相对柔度较大、孔数较多时,要不超过允许的计算精度,解方程组的工作量仍很大。当然,利用电算是解决连拱计算问题的合理办法,然而在电算设备还不够普遍的情况下,改进连拱的计算理论,仍有一定的现实意义。本文介
I. INTRODUCTION 1 INTRODUCTION The idea of solving the arch problem by the angular displacement method is the simplest. However, when the number of holes is large, it is a heavy workload to solve large linear equations. For this reason, many scholars put forward various simplified approximation methods. They either reduce the number of holes calculated or try to reduce the number of elements in the system. However, when the relative flexibility of bridge piers is large and the number of holes is large, the allowable calculation accuracy will not be exceeded, and the workload of solving the system of equations is still very large. Of course, the use of electricity is a reasonable solution to the problem of arching calculation. However, it is still of practical significance to improve the theory of arcades when the computing equipment is not yet universal enough. This article describes
