位于圆曲线上桥墩点位的传统测设方法比较麻烦,现介绍一种简便的测设方法。如右图所示,AB为桥梁中心线,0-1、0-2、……4-1、4-2点为桥墩中心位置。0-1、1-1、……4-1各点位于同一个圆曲线上,半径为R+b/2;0-2、1-2、……4-2 The traditional measuring and measuring method located at the piers on the circular curve is rather troublesome. A simple measuring and measuring method is now introduced. As shown on the right, AB is the bridge center line, 0-1, 0-2, ... 4-1, 4-2 points for the center of the pier. 0-1, 1-1, ...... 4-1 Each point is on the same circle curve, the radius is R + b / 2; 0-2, 1-2, ...... 4-2
