摘要
为合理规划设计渣场容量,采用现场取样试验,研究了大中型水电工程堆渣的堆实系数。对于不同的渣料,重点研究了土渣料、石渣料、土石混合渣料、砂砾石渣料的堆实系数,最终获得渣场堆实系数随粒径的变化规律,及不同渣料的堆实系数取值范围。由试验所得的大中型水电工程渣场堆实系数,能为渣场规划设计提供科学依据,对确定经济合理的渣场规划方案、减少渣场占地、节约土地资源、降低征地移民难度、减小工程投资具有重大的意义。
For planning and designing the stockpile volume rationally, field sampling experiment is adopted to study the stockpiling coeffi- cient of excavated materials on the large and medium-sized hydropower projects. The research is mainly focused on the stockpiling coefficient of the soil, the excavated rock material and the soil-rock mixture and the sandy gravel. Results reflect the variation trend of the stockpiling co- efficient following the change in the particle size, and the stockpiling coefficients are obtained for different materials. A reasonable stockpiling coefficient provides reliable design basis for stockpile area planning. It has the significant value for the planning and designing of stockpile volume, reducing the occupied land of stockpile, saving land resources, reducing the difficulty of settlement and requisition of land and re- ducing project investment.
