哈拉布拉钢筋混凝土面板坝面板混凝土裂缝控制

Cracking control on slab concrete of reinforced concrete slab rockfill dam for Halabula Reservoir

结合哈拉布拉水库钢筋混凝土面板坝工程实际,探讨通过采取优化面板混凝土配合比、改进面板混凝土的施工方法与施工工艺、调整面板混凝土的养护方式、加强面板混凝土的施工质量控制等措施,从而提高面板混凝土的抗裂能力,减小对面板的外部破坏力,使面板混凝土的裂缝得到有效控制。

Based on the construction of Halabula Reservoir Project, the construction method and technology are improved through the optimization of the mixing proportion of the slab concrete, and then the method for curing the slab concrete is adjusted and the quality control of the construction of the slab concrete is strengthened, thereby, the cracking resistance of the slab concrete is enhanced with the decrease of the outside damage force on the slab, and finally, the cracking of the slab concrete is effectively controlled as well.
