用最小二分法进行已知两端点及半径圆弧测设

On circular arc survey on known two ends and diameter by minimum dichotomy

针对施工中常会遇到的圆弧造型放线工作,且直接从圆心放圆弧并不现实的问题,介绍了一种简单易行的放线方法,即最小二分法,通过工程实例,对如何用最小二分法进行已知两端点及半径的圆弧测设进行了说明。

Aiming at alignment of the circular form in construction and the unreal problem which has the circular arc from the circle center,the paper introduces the easy and feasible alignment,the minimum dichotomy method, through engineering example,and indicates the way of how to have the circular arc survey on known two ends and diameter by minimum dichotomy method.
