【摘要】：输电线路工程线路长、空间跨度大、扰动分散,造成水土流失呈点状分布,使得布设样点监测输电线路工程的水土保持状况极为困难。以糯扎渡送电广东±800 k V直流输电工程(云南区)为例,利用分层抽样和预监测的方法计算出水土保持监测样点的样本容量,并采用适度法对样本容量进行分配,提出了结合施工现场的输电线路水土保持监测样点布设方案,结果可为同类地区线型工程水土保持监测样点的布设提供依据和参考。
[Abstract]:Because of the long transmission line, large space span and scattered disturbance, the soil and water loss is distributed in the form of points, which makes it very difficult to monitor the soil and water conservation of transmission line project by setting up sample points. Taking Nuozhadu 卤800kV HVDC transmission project (Yunnan area) as an example, the sample capacity of soil and water conservation monitoring sample is calculated by stratified sampling and pre-monitoring, and the sample capacity is distributed by appropriate method. In this paper, a scheme of monitoring sample points for water and soil conservation of transmission lines combined with construction site is put forward. The results can provide the basis and reference for the layout of soil and water conservation monitoring sample points of similar projects in the same area.
