徐村电站砾质土防渗体的大型试验研究
|
摘要
文章就徐村电站砾质土现场大型击实和碾压试验成果进行了系统的分析,得出了徐村坝料的最优施工碾压参数、含水量控制范围及砾石含量上限值,评价了设计标准各项指标的合理性。结合有关类似工程试验成果,建议了一种砾质土最大干密度、最优含水量及现场压实质量检测较为合理的方法和经验公式,并对砾质土的一些工程特性做了详细分析。
This paper has obtained the optimum dam construction and roller compaction parameters, moisture content control variation and gravel content upper limit of the Xucun dam materials, and evaluated the rationality of all the design standard-based indexes by carrying out systematic analysis of in-situ large scale gravelly soil compaction and roller compaction test results for the Xucun hydropower project. The paper recommends a rational method and an empirical formula of checking the gravelly soil max. dry density, optimum water content and in-situ compaction quality with reference to the test results for other similar projects. The paper has also made a detailed analysis of some engineering characteristics of gravelly soil.
