缓和曲线测设中克服视线障碍的分析计算

Analysis Calculating of Overcoming the Sight Obstruct in the Transition Curve Surveying and Design

本文采用微分计算,推导出迥旋线任意微弧段坐标值计算的积分公式,当采用迥旋线作为道路的缓和曲线时,利用此公式可以保证缓和曲线的连续测设,从而克服因测设视线障碍带来的困难.

Using integral calculating the paper derives the integral formular of calculating the coordinate value of spiral curve arbitrary micro-length,by which can ensure contin- uous surveying of the transition curve and overcome the difficulties caused by sight obstruct.
