摘要
施工过程是碾压层内力学参数渐变的直接影响因素,然而,在碾压混凝土坝施工的过程中,由于影响因素众多及工艺的局限性,其实际层面影响带参数渐变往往偏离理想的分布形式,不再是准确的呈指数衰减分布,而有可能近似呈指数型变化.基于碾压层内弹性模量分布特征,提出了碾压层弹性模量理论解,为评价大坝安全性态提供了可靠的依据.
The construction process is the immediate factor that causes the mechanics parameter of the roller compaction layers changes gradually; however, in a roller compacted concrete dam（RCCD） construction process, owing to the limitation of the technology and many influences on the process, its actual gradual changes of the effect zones＂ parameter often deviates the ideal distributed form, not assuming the exponential decay distribution accuratly; but it is possible to be approximate to the type of exponential change. Based on the distribution features of the elastic modulus of RCCD layer, theoretical solutions of the elastic modulus of RCCD layer are proposed.
