在江垭大坝碾压混凝土筑坝施工中，为了充分发挥碾压混凝土施工优势，进一步提高施工效率和施工质量，克服仓面面积大和浇筑能力小的矛盾，在大坝１６４ｍ高程以上采用了全坝面平行坝轴线方向的斜层平推铺筑法。应用这种方法，可以把层间间隔时间控制在２～４ｈ以内，施工效率大大地提高。钻孔取样检查表明，施工质量与传统方法相比达到了同一等级标准水平，有些方面还略显优越。实践证明，斜层平推铺筑法是一种科学合理的施工方法，具有广泛的应用前景
In the dam construction of RCC dam, in order to give full play to the advantages of RCC construction, to further improve the construction efficiency and construction quality, to overcome the contradiction of large storage area and pouring capacity, the dam above the 164m elevation using the whole Oblique slab paving and paving method in the direction of parallel dam axis. Application of this method, the interval between layers can be controlled within 2 ~ 4h, the construction efficiency greatly improved. Drilling sampling inspection showed that the construction quality compared with the traditional method has reached the same level of standard level, but also slightly superior in some aspects. Practice has proved that the inclined layer of flat push paving method is a scientific and rational method of construction, with a wide range of applications
