在水利堤防工程及道路工作测量中,由于地形变化,从而工程施工路线也发生相应变化。在变化处,按设计规范规定,通常用曲线连接。这是为了降低水利工程堤防建设中,由于路线变化从而改变水流方向,对堤岸的冲刷;在道路方面,是为了保证行车安全。下面介绍在公路施工中,常见的两种曲线:缓和曲线和圆曲线。 一、缓和曲线 缓和曲线是连接圆曲线和直线段而特设的曲线段,是直线段与圆曲线
In the water conservancy embankment project and road work measurement, due to the terrain change, so that the construction of the corresponding changes in the route. In the changes, according to the design specifications, usually with a curve connection. This is to reduce the embankment construction of water conservancy projects, as the route changes to change the direction of water flow, the embankment erosion; in the road, is to ensure traffic safety. The following describes two common curves in highway construction: easing curve and circular curve. First, the ease of the curve Moderate curve is connected to the circular curve and straight line segment and the ad hoc curve segment is the straight line segment and the circular curve
