基于工程体与地质体相互作用的两体力学模型初探
STUDY ON TWO-BODY MECHANICAL MODEL BASED ON INTERACTION BETWEEN STRUCTURAL BODY AND GEO-BODY
【摘要】 针对大坝和坝基、坝肩和库岸相互作用传统的一体两介质模型,提出了两体力学模型的基本概念、研究思路以及应用范围;阐述了一体两介质力学模型与两体力学模型之间的差异,并用单轴压缩实验进行了验证;建立了重力坝和坝基相互作用的两体力学模型,为大坝与坝基的整体稳定性研究与评判提供了一条新的途径。
【Abstract】 The interactions between gravity dams and foundations or arch dams and canyons are important for stability of dams. Based on the conventional interaction bimaterial model of dam and foundation,the two-body mechanical model is presented including the basic concept,method and application scope. The difference of bimaterial model and two-body model is verified by uniaxial compressive tests. The two-body mechanical model of dam and foundation is presented in order to provide a new method for stability analysis of dam and foundation.
