【摘要】：輸電線路工程線路長、空間跨度大、擾動(dòng)分散,造成水土流失呈點(diǎn)狀分布,使得布設(shè)樣點(diǎn)監(jiān)測輸電線路工程的水土保持狀況極為困難。以糯扎渡送電廣東±800 k V直流輸電工程(云南區(qū))為例,利用分層抽樣和預(yù)監(jiān)測的方法計(jì)算出水土保持監(jiān)測樣點(diǎn)的樣本容量,并采用適度法對樣本容量進(jìn)行分配,提出了結(jié)合施工現(xiàn)場的輸電線路水土保持監(jiān)測樣點(diǎn)布設(shè)方案,結(jié)果可為同類地區(qū)線型工程水土保持監(jiān)測樣點(diǎn)的布設(shè)提供依據(jù)和參考。
[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 鹵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.
