【摘要】 通过对云南省9个大中型输变电工程水土保持方案的编制工作,分析了在输变电工程建设期产生水土流失的主要特点,分析结果表明施工便道区是输变电工程产生水土流失的重要区域,其水土流失量约占总量的55.69%,单位线路的输变电工程在建设期产生的水土流失量为25.03 t/km。此外,通过Matlab软件对输变电工程水土流失量及施工便道区水土流失量与输变电工程线路长进行最小二乘法拟合,拟合结果较好。并定量和定性地分析了输变电工程水土流失的特点,以期为同类工程的水土流量预测提供一定的理论依据。更多还原

【Abstract】 The authors analyze the characteristics of transmission engineering construction period on the basis of completing plan of soil and water conservation in the nine large and medium-sized power transmission engineering in Yunnan province.It is found that the service road is nearly 55.69% of the gross of soil and water loss,and it is the main site for soil and water loss. The results show the soil and water loss is 25.03 t/km in the power transmission engineering construction period.The Least Square Method in the Matlab software is used to determine the relationship between the length of power transmission engineer- ing and the gross of soil and water loss,also the other relationship between the length of power transmission engineering and a- mount of soil and water loss in the service road.Both of qualitative analysis and quantitative analysis are used for the character- istics in the power transmission engineering.And the paper can be the theoretic reference for other analogous engineering.更多还原
