Research on Influence of Roughness on Shear Characteristics of Interfaces Between Frozen Soil and Structures
-
摘要: 随着西部大开发和振兴东北战略进一步深化,各种寒区工程得以大规模修建。为了保证建、构筑物的寿命,使其在服役期内能够保持正常的工作状态,要求冻土和结构物具有良好的冻结强度和稳定性,冻土-结构接触面特性是冻土力学特性最直接的反映,而接触面粗糙度是影响这一特性的重要因素。因此主要从粗糙度出发,根据国内外现有冻土-结构接触面剪切试验研究成果,从粗糙度的评定、粗糙度对力学特性的影响及其微观机理等方面进行了系统的分析;最后基于Gompertz模型构建了可考虑粗糙度影响的接触面剪应力-剪切位移本构模型,验证表明,该模型能够较好地描述接触面的剪应力-剪切位移发展规律。Abstract: Large scale construction projects have been carried out on varieties of cold areas with deepening of the Western Development and the Northeast Revitalization Strategy. To ensure the life of construction projects and maintain their normal working states in service periods, the higher bearing capacity and stability are needed to keep for frozen soil and structures. It is characteristic of frozen soil-structure interfaces that the frozen mechanics is the most direct mirror, and the roughness of interfaces is one of important factors influencing characteristics. Therefore,taking roughness as an influencing factor, based on the existing scientific research achievements of shear test research on frozen soil-structure interfaces at home and abroad, it was systematically analyzed from roughness evaluation, effect laws of roughness on mechanical properties and microscopic mechanisms. Based on the Gompertz model, a constitutive model between shear stress and displacement on interfaces was presented by considering the effect of roughness, which could well describe the evolution laws between stress and displacement of interfaces.
