As power market demand becomes increasingly pronounced,the 110 kV power network develops rapidly in the recent years.The power network building increases soil loss from the construction area.The causes and characteristics of soil loss caused by overhead power transmission lines construction were analyzed.Combined with the project case,prevention zones were divided based on the features of the project area and project construction.Soil and water conservation measures were then proposed based on the divided zones.Result from the study is helpful to give a supplement and perfection to soil and water conservation in overhead power transmission lines construction and provide construction unit with scientific references to effective soil and water conservation.
