围滩水电站自密实堆石混凝土劈裂抗拉性能试验分析

Test Analysis of the Cleavage and Tensile Performance of the Self-compacting Rock-filled Concrete in Weitan Hydropower Station

围滩水电站大坝采用自密实堆实混凝土,为了验证该技术的可行性,在工地现场直接从自密实堆石混凝土大型试件上进行试块切割,而后进行了劈裂抗拉性能试验研究,试验结果劈裂抗拉强度平均值为1.75MPa,完全满足工程等级要求。

The self-compacting rock-filled concrete is used to construct Weitan Hydropower station.In order to verify the feasibility of this technique the large samples are directly cut from the self-compacting rock-filled concrete on site,then the study on the cleavage and tensile performance is conducted.The results show that the average cleavage and tensile performance is 1.75MPa.It fully meets the requirements of engineering.
