摘　　要：为解决岩土工程中在复杂应力路径下土体-结构界面复杂接触变形行为问题,根据三轴试验仪可以提供复杂外部荷载条件的能力和在土体中嵌入结构材料的可行性特性,提出了借助三轴试验仪测试复杂应力路径下界面行为的试验方案,推导了特定条件下界面行为的接触分析解,给出了确定双曲线模型参数的方法。结果表明,这种三轴界面试验方案可以很好地描述复杂应力路径下土体-结构界面的复杂变形行为,并能够方便地应用于土体-结构相互作用分析中.In order to solve the complex contact deformation problems of soil-structure interface under complex stress path in geoteehnical engineering, according to the capability of triaxial apparatus in supplying complex exterior load condition and the feasibility feature of structure material being embed in soil, a interracial testing design under complex stress path is developed in virtue of triaxial apparatus. And, a contact analysis solution of interfacial behavior under certain condition is derived and a method to obtain hyperbolic model parameters is given. The result shows that the triaxial interracial testing provides a good description of soil-structure complex interfacial behavior under complex stress path, and the design can be applied to the analysis of soil-structure interaction easily.
