本文介绍用单变数一次求解法验算带圆端的矩形桥墩截面大偏心受压强度方法简便,勿需反复假定,一次即可求解,可大大简化计算工作。作者详细推导了计算公式,并结合实桥计算举例,其结果与试算法相比较,精确度在98％以上。有一定实用价值,可供桥梁设计人员参考。 In this paper, it is simple and easy to calculate the large eccentric compressive strength of the section of a rectangular piers with circular ends by the single-variable one-time solution method. Without repeated assumptions, the solution can be done once, which can greatly simplify the calculation work. The author deduced the formula in detail, and combined with real bridge calculation examples, the results compared with the trial algorithm, the accuracy of more than 98%. A certain practical value, for bridge designers reference.
