摘要
在道路、管道、地下工程、场地平整等工程施工中,经常需要在地面上测设设计的坡度线。工程测量中已知坡度线的测设大都采用倾斜视线法,考虑到实际施工工作中精度和效率等因素,提出采用扇形视线法测设坡度线,文中对该方法的使用注意事项做详细的介绍。通过实际施工应用,证明扇形视线法具有较高的应用价值。
In the laying of pipelines, road construction and site formation works, we often need to do grade location. In engineering survey, the tilt line of sight method is often used to locate the known slope of the line. Taking into account the actual construction work factors such as accuracy and efficiency, this paper discussed the fan-shaped line of sight method. The method used is detailedly introduced. Through the actual construction applications, fan-shaped line of sight method has higher value.
