双江口水电站心墙防渗土料两种掺合方案对比分析

Comparison Analysis on Two Mixing Schemes for Dam Core Earth Materials at Shuangjiangkou Hydropower Station

在应用天然建筑材料筑坝时,一些材料不能满足工程要求,如防渗或力学指标,需要通过采取工程措施(如掺合砾石料)对防渗土料进行改性。对两种掺合方案和施工工艺进行了分析讨论,探讨了两种掺合防渗料的物理力学特性和现场掺合试验效果。

When natural materials are used to build a dam,some materials will not meet engineering requirements,such as imperviousness and mechanics index,therefore,impervious earth material needs to be improved by taking engineering measures(adding gravel material).Two mixing schemes and construction techniques are studied and discussed in this paper.Physical mechanics property and site mixing test results for two mixing impervious materials are presented.
