碾压混凝土坝施工质量风险评价研究

Risk evaluation of construction quality of roller compacted concrete dams

为提高碾压混凝土坝施工质量管理水平,从压实容量、抗压强度、耐久性、受力变形特性、层面的结合性能等5个方面构建施工质量风险初始评价指标;利用专家甄别以及相关性分析方法得到最终评价指标;构建灰色多层次评价模型对碾压混凝土施工质量进行评价,并通过评价结果判断施工过程中存在的问题。

In order to improve the management level of construction quality of roller compacted concrete( RCC) dams,the initial evaluation indexes of risk of construction quality are established including compaction capacity,compressive strength,durability,deformation characteristics and combination of layers.The expert evaluation and the correlation analysis are used to obtain the final evaluation indexes. The grey multi-level evaluation model is established to evaluate the construction quality of RCC dams,and the existing problems in the construction process are judged by the evaluation results.
