easement curve

基本解釋

Easement curve was introduced, whereby curvature changes steadily form a straight line to the desired radius.
緩和曲線推出，即曲率變化，穩(wěn)步形成一條直線，以達(dá)到預(yù)期的半逕。
It presents the rigorous method to calculate the intersecting point coordinate of the straight line with the parallel to the easement curve.
提出了計(jì)算直線與緩和曲線平行線交點(diǎn)座標(biāo)的嚴(yán)密方法。
A new calculating formulae is suggested for selecting curveradius in horizontal realinement under the condition of unchanged length of easement curve.
另外建議一個(gè)在既有緩和曲線不改動(dòng)時(shí)計(jì)算曲線半逕的公式。
