| Abstract: | By using the methods of site investigation and local observation,the paper researched the bulk weight of the residue soil,the composition of residue particles,the amounts of soil erosion at the original physiognomy,greening slope,loose debris slope of dumpling pile and the residue stacking platform and residue transport access road in Jin-Anqiao hydropower station project respectively.The result shows： ①the mean values of the bulk weight of the residue in the different zones of excavation waste dump are 1.70 g/cm3,1.30 g/cm3 and 0.96 g/cm3,respectively;②After removing the stones of which the particle diameter 2 cm,the percentage of spoil particles diameter 4 mm is 57.09%,which is 14.31 % higher than that of the farmland surface soil;③The mean amounts of soil erosion at abandoned ladder platform and shrub land are 47.3 t/km2 and 114.2 t/km2,respectively;④The mean amounts of soil erosion at overburdened and non-overburdened greening slope are 40.5 t/km2 and 74.6 t/km2,respectively;⑤The amounts of soil erosion at the residue stacking platform and residue transport access road and non-cut drainage measure and cut drainage measure residue stacking side slope are 94,280 and 96 times more than the mean of amount of original physiognomy,respectively. |
