摘要

摘要: 采用大型静动力简单剪切仪,对某面板堆石坝灰岩堆石料进行了动剪切模量阻尼比试验和动残余变形试验。试验资料表明,堆石料的模量阻尼特性采用修正等价黏弹性模型描述可取得较好效果。考虑到在围压和动应力比较高时,残余应变与振次的关系和半对数规律偏差较大,采用幂函数描述残余应变的发展,建立了以平均主应力、固结应力比和动剪应变为自变量的残余变形计算模型。通过拟合不同堆石料的试验结果,表明该模型具有较好的适用性。

Abstract: Large-scale cyclic simple shear tests on rockfill materials of limestone are performed to study the characteristics of dynamic moduli, damping ratios and residual deformations. The experimental results show that the curves of G_d/G_dmax~γ_d and λ/λ_max~λ_d are described by the modified nonlinear viscoelastic dynamic constitutive model. When the confining pressure and dynamic stress ratio are higher, the relationship between residual strain and numbers of cycles diverges the semilog rules evidently. Based on the test data, a power function is adopted to describe the development of residual strain. Then a residual strain model is proposed, which is a function of the average main stress, consolidation ratio and dynamic shear strain. By analyzing the collected test results, the feasibility of this model is validated.
