施工中,在施测道路转弯处时,常碰到障碍物(如图1)。怎样把弧上各点测设于实地呢?下面介绍具体方法。将图1转弯处另绘实地测设的曲线图,如图2所示。这一曲线测设分为3个步骤: (1)所需曲线元素T、E、C、M、 Construction, in the detection of road turns, often encounter obstacles (Figure 1). How to set the spot on the spot in the field? The following describes the specific method. Turn the curve at Figure 1 to draw a diagram of another plot, as shown in Figure 2. This curve measurement set is divided into three steps: (1) the required curve elements T, E, C, M,
