| 摘 要： | 大峡水电站大坝施工采用全断面通仓簿层连续上升施工工艺,该工程采用人工砂石骨料,将石粉含量控制在13%～17%,改善了碾压混凝土的特性.根据河床狭窄、两岸陡峭的特点,混凝土入仓采用汽车直接入仓、负压溜槽入仓相结合的方法,用了12个月的时间,完成了碾压混凝土浇筑任务.经检测结果表明大峡大坝碾压混凝土的各项性能指标均满足设计...

| Abstract: | The application of thin-layer full-section and full-surface area placement technology in the dam of Daxia hydropower station is described in the paper.The project adopts the artificial sandstone aggregate with the 13%～17% content of stone powder,which improve the characteristics of characteristics of the roller compacted concrete.According to the features of the narrow river bed and the steep banks,the combination method of automobile directly placement and vacuum pipe placement are used to enter the dam,then the construction task is completed within 12 months.The test results show that the performance indicators of Daxia dam can meet the design requirement. |
