A Study of Strength Parameter Evolution and a Statistical Damage Constitutive Model of Cemented Sand and Gravel

Abstract: Cemented sand and gravel (CSG) has a wide range of applications in dam construction, and its properties are between rockfill and roller compacted concrete (RCC). A difference in gel content will result in a variance in CSG’s structure and mechanical properties. To investigate the intricate structural mechanical properties of CSG, this study conducted a series of laboratory tests and associated discrete element analyses. Accordingly, the evolution law of the strength parameters of CSG is explored and a statisti… Show more

“…Scholars from both China [17][18][19][20][21][22] and abroad [23][24][25][26][27] mainly use finite element and discrete element numerical simulation methods to model the mechanical behavior of glutenite during force loading. Guo et al [17] established an evolutionary function between strength parameters and strain-softening parameters and simulated the dynamic stress-strain behavior of samples with different cement strengths. Zhang et al [18] and Liu et al [19] used the finite element method to simulate and analyze the effects of gravel size and strength characteristics on the mechanical parameters of glutenite.…”
