厦门莲花水库主坝碾压混凝土配合比优化研究

Analysis on RCC Mix Proportion Optimization of Main Dam of Xiamen Lianhua Reservoir

本文以厦门莲花水库工程为例,介绍了在地材受限,碎石超逊径含量高、级配严重不良情况下,通过增加其它规格的碎石、调整碎石比例、调整用水量和粉煤灰用量,提高砂率的方法来优化碾压混凝土配合比,以为其它类似工程碾压混凝土配合比设计和优化提供借鉴。

In this paper,taking the project of lianhua reservoir in xiamen as an example,introduces the ground material limited,high content of gravel diameter super Nicholson,grading,serious adverse circumstances,by adding other specifications of rubble,the adjustment proportion of gravel,water usage and dosage of fly ash,improve the sand ratio method to optimization of the mix proportioning of the RCC and RCC mix design of other similar projects and optimization for reference.
