自密实堆石混凝土梁的正截面受力性能

Behavior of Self-compacting Rock-fill Concrete Beam under Normal Section Stressing

为了研究用自密实混凝土充填堆石体后所形成的堆石混凝土梁在静荷载作用下的工作性能,本文完成了两个自密实堆石混凝土梁的三分点加载试验,并对其正截面受力特性进行了较为详细的分析。试验证明:自密实堆石混凝土梁在静荷载作用下整体性能良好,其正截面受力性能符合平截面假定。

In order to study the behavior of the self-compacting rock-fill concrete beam under static load, two tests of the three-dividing point loading are done. The behavior of the self-compacting rock-fill concrete beam under normal section stressing is analyzed in detail. The experiment proves that the integrity of the self - compacting rock-fill concrete beam is well and the assumption of the horizontal section is suit to the study on the selfcompacting rock-fill concrete beam.
