在村镇规划建设尤其是山区的规划建设工作中,由于地形地貌的特殊条件,道路的弯道设置比较多,在实施村镇建设规划时,道路曲线部分的定点放线成了村镇建设技术员经常遇到的问题,而以往的放线方法多数比较繁琐,准确性不高。为了适应村镇建设的新形势,推动村镇建设的发展,今介绍一种道路曲线放线的简便方法,以供广大村镇建设技术员应用。 已知道路两条直线段的夹角α及道路两直线段中线交点A的位置。(如图1)
In the planning and construction of village and town planning, especially in mountainous areas, due to the special conditions of topography and landform, the corners of the road are set more. When implementing the planning of village and town construction, the fixed point payout of the curvilinear part of the road becomes a common problem encountered by village and town construction technicians The problem of the past, most of the pay-off method is more complicated, the accuracy is not high. In order to adapt to the new situation of village and town construction and to promote the development of village and town construction, a simple and convenient method for releasing the curve of the road is introduced for the application of the vast number of village and town construction technicians. It is known that the angle α between two straight-line sections of the road and the intersection point A of the middle line of two straight-line sections of the road. (Figure 1)
