摘要
为模拟碾压混凝土坝层面的影响,通过建立薄片计算模型,利用最小势能和最小余能原理,推求出碾压混凝土坝层面影响带厚度范围,并提出了实际层面影响带厚度的确定方法。这使坝体应力、变形和渗流等分析计算有了科学依据。
In order to evaluate the behaviors of roller-compacted ooncrete dam(RCCD) conjoint layer, the sheet model of RCCD is established. Applying the least potential energy principle and the least complementary energy principle, this paper presents formulas for determining the range of effect-zone thickness of RCCD, and the method of determining virtual effect-zone thickness is put forward. The result may be applied to the analysis of RCCD.
