断面法测量计算的精度与间距L的长度有关,L越小,精度就越高。但是这种方法测量工程量大,尤其是在范围较大、精度要求高的情况下(如轨道交通工程车辆段)更为明显;本文从实际工程施工中摸索,在采用断面法测量时,结合合同文件、设计图纸等资料,从施工角度通过断面设置(L)、截面计算(S),较理想的减小精度与速度的矛盾,达到了较优化的组合效果。
The accuracy of the cross-sectional measurement calculation is related to the length of the spacing L. The smaller the L, the higher the accuracy. However, this method has a large amount of measurement engineering, especially in the case of large range and high precision (such as rail transit vehicle depot). This article explores from the actual construction, when using the cross section method, Contract documents, design drawings and other information from the construction point of view through the cross-section set (L), cross-section calculation (S), the more ideal reduction of accuracy and speed of the contradiction, to achieve a more optimal combination of results.
