户宋河电站主坝土料填筑质量控制与检测成果分析

Main Dam Earth Material Placement Quality Control and Monitoring Results Analysis for Husonghe Hydropower station

户宋河电站主坝设计为Ｌ型排水体的均质坝，该坝就地取材，是我省首次采用风化花岗岩土料填筑的土坝。施工中监理、施工单位及复核单位对大坝进行了全面的、科学的、规范化的质量控制与监测。监测结果表明，填筑质量好，各项指标完全满足设计要求，总合格率为９８．４％。经一年蓄水和观测表明，主坝运行正常。

The main dam of the Husonghe Hydropower Station is a homogeneous earth structure with a L_shaped drainage system, which is the first dam embankment built using the locally available weathered granite earth material in this province. During construction of the dam the construction supervisor, the contractor and the monitoring agency carried out an overall, scientific and standardised quality control and monitoring of the dam embankment. The monitoring results indicate that all of the indexes of the earth placement fully satisfied the design requirements and the quality qualification rated is 98.4%. The one year's impounding and observation proved that main dam is functioning normally.
