井子水库堆石坝填筑碾压试验及结果分析

Rolling Test and Result Analysis of the Jingzi Reservoir Rockfill Dam

为了复核堆石坝填筑设计标准的合理性,确定达到设计标准的压实方法,在大坝主体工程施工前,需要对不同填筑区填筑材料进行碾压试验。通过对井子水库各填筑区碾压试验方法、试验过程的阐述,以及对碾压试验结果的分析,确定了适用于本工程大坝填筑的施工机械、铺料厚度和碾压遍数等施工参数。

In order to review the rationality of the design criteria for rockfill dam filling and determine the compaction method to meet the design criteria,it is necessary to carry out rolling tests on the filling materials in different filling areas before the construction of the main works of the dam.Through the elaboration of the rolling test method and process of each filling area of the Jingzi Reservoir and the analysis of the rolling test results,the construction parameters such as construction machinery,paving thickness and rolling times suitable for the dam filling of this project are determined.
