摘要
对现场碾压混凝土(RCC)剪切试验结果的分析,发现存在有剪切强度离散性、局部骨料的架空、剪切时拉伸.τ～△μ的多样性、剪切面的不同破坏模式等现象.对这些现象进行了总结分析,指出应通过铺摊均匀和改善碾压条件来提高碾压层面的质量,使其抗剪强度均匀一致,还利用残余抗剪强度参数对碾压坝体进行了稳定性计算分析.
The analysis on the field sheafing testing results of roller compacted concrete （RCC） has shown that RCC exhibits, during testing of dicrete sheafing strerenth, local voids of aggregate, tension when sheafing and different failure patterns on shearing plane. The analyzing results of the aforesaid phenmena point out that the quality of the roller surface should be raised through even paving and improving roiling condition so as to make the sheafing strensth uniform. The stability calculation analysis has been conducted on the roller compacted dam body using the residual sheafing strength index quality.
