高拱坝全级配混凝土动态试验研究

大坝混凝土动态性能试验为当前高拱坝建设亟待解决的一个关键问题。纵观国内外为数不多的大坝混凝土动态试验，都是采用湿筛混凝土在无初始荷载条件下进行的，试验测定的指标并不能真正反映大坝混凝土的实际性能。为此，开展高拱坝受力特征条件下大南全级配仿真混凝土抗压和拉动态参数及不同始静载影响的试验研究，具有重要的工程应用前景和促进学科发展的作用。

Dynamic tests and study on the fully-graded concrete for high arch dam

The dynamic performance test of dam concrete is a key problem to the construction of high arch dam at present. As viewed from a few dynamic tests of dam concrete at home and abroad, the wet screened concrete was used in all tests under the conditions of no initial load, so that the measured indexes from those tests could not truly reflect the actual performance of the dam concrete. Therefore, the test and study on the dynamic compressive, bending and tensile parameters of fully graded concrete under the load conditions of high arch dam or under the conditions of different initial static loads has important application prospect and is suitable to promote the development of this discipline.
