五一水库大坝优化设计的探讨

Discussion on the Design Optimization of the Wu Yi Reservoir Dam

根据坝址区地质条件及当地建材的性质、储量,经前期坝型比较分析,确定坝型为粘土心墙风化料分区坝。经料场复查及碾压试验验证,结合料场开采规划,根据基础开挖揭露的实际地质情况,对大坝进行了优化设计。五一水库2010年9月蓄水至正常水位,2012年6月通过了工程竣工验收,水库蓄水运行良好。

A clay core wall weathered material zoned dam was chosen for WU Yi reservoir through comparison and analysis of the dam types in the early stage according to the geological conditions of the dam site and properties and reserves of local building materials. The design of the dam was optimized later after re-examination of the borrow area and verification by roller compaction test according to the actual geological conditions exposed by foundation excavation taking into account of the borrow planning. The reservoir impounded water up to the normal storage level by September, 2010 and passed the final acceptance in June, 2012. The reservoir has been under proper operation.
