堆石自密实混凝土在水库重力坝施工中的应用分析

Analysis on applying rock-fill self-compacting concrete in reservoir gravity dam construction

混凝土堆石重力坝因其耐久性好、安全可靠等诸多优点被广泛应用于各类水工建筑物拦水大坝中。本文以某水库大坝为例,从材料选择到施工重点详细分析了坝体施工中大体积混凝土现浇受温度和收缩影响较大而需要注意的问题,同时通过施工介绍更直接地阐述了堆石坝的技术优越性。

Concrete rock-fill gravity dam has many advantages of good durability,safety,reliability,etc.,which can be widely applied in various water retaining dams of hydraulic structures. In the paper,a reservoir dam is adopted as an example. Problems from material selection to construction focus are analyzed in detail,namely large volume concrete castin-situ in dam construction is greatly affected by temperature and shrinkage,and the problems should be emphasized.Meanwhile,technical superiority of rock-fill dams is described more directly through construction introduction.
