The Calculation method of earth-rock allocation balance and its application for the pumped storage hydropower construction

摘要

There is a large number of excavation and filling in the construction of pumped-storage power station, and the filling materials are from the excavated materials. The construction planning is limited by the space, time and quantity, order, and its procedure directly affects the construction schedule. Based on relationships analysis of construction schedule and material quality, quantity and its balance, the spatial coordination of excavation, embankment partition and construction safety distance, three models are established which are excavation volume calculation model, the processing logic model and the excavate-transport-fill analysis model of earth-rock. Also, the dynamic balance and allocation of earth-rock for the main work construction are realized. The case analysis shows that this study will contribute to the management efficiency of project construction.
