浅析虚测设圆曲线半径确定法

Analysis of the definition of the virtual measurement of the curve radius

本文在论述传统教材中虚交圆曲线测设同时,着重讨论了虚交中圆曲线位于基线内、外侧的临界半径值的确定,以及如何通过有利地点确定理想的曲线半径,同时给出相应的计算公式。

The paper expounds the measurement of the virtual intersection of the circular curved line in the traditional teaching materials.It mainly discusses the definition for the critical radius when the circular curved line is situated outside and inside the base line in virtual intersection. As well as how to definite the radius by the site. It also gives the relevant calculating formula.
