摘要
通过双峰寺水库工程现场碾压混凝土(RCC)试验块的剪切试验,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~Δμ的多样性、剪切面的不同破坏模式等现象。提出了施工方在试验块碾压过程中层间铺设时间间隔不够等原因造成的。
Through the field of roller compacted concrete (RCC) test block shear test, found that there are shear strength discreteness, local aggregate overhead, shear tensile, the diversity of r-hg, the different failure modes of shear surface phenomenon. Analysis of these phenomena, and points out that caused by time interval of laying interlayer was not enough by the construction side in the test piece rolling process.
