浅谈城市道路缓和曲线的测设

Talking about Measuring and Setting of Transition Curve of Urban Road

结合太原市康西路的具体情况,描述了城市道路缓和曲线的测设。通过采用测距仪和极坐标方法,利用施工导线放取道路缓和曲线的主要点,采用偏角法对道路缓和曲线布点进行详细测设,有效地提高了各主要点的点位精度,减少了测设中的误差,保证了道路缓和曲线线型的圆滑。

Connecting with the concrete situation of Kangxi Road of Taiyuan City, this paper describes the measuring and setting of transition curve of urban road. Making use of the construction guideline to lay off the major points for the transition curve of the road with the distancer and polar method, and making the measuring and setting in detail of the points on the transition curve of the road with declination method, can increase effectively the accuracy of the points' location of all major points, reduce errors in the measuring and setting, and guarantee the smooth of the transition curve of the road.
