上海典型土层与混凝土接触特性的试验研究

Experiment on Interaction between Typical Soils in Shanghai and Concrete

利用直剪试验 ,结合上海典型土层 ,分别在饱和和水下 2种情况 ,对褐黄色粉质粘土、粘质粉土、淤泥质粘土、灰色粘土、灰色粉质粘土、暗绿色粉质粘土和草黄色砂质粉土与混凝土的相互作用 ,进行了试验研究 ,得到了几种典型土体与混凝土相互作用的切向位移应力关系、法向位移应力关系、摩擦角、粘聚力、破坏比以及初始切向法向刚度 ,从而为相关问题的数值模拟提供了参数依据 .

With single shear box,typical soils in Shanghai were experimented on interaction between soil and concrete,besides,interaction between saturated soils,soils under water and concrete was tested respectively.The relations of displacement-stress in tangent and normal direction,friction angle,cohesive,failure ratio,initial tangent stiffness and initial normal stiffness were proposed through this experiment,so this experiment plays an important role on numerical simulation for relative studies.
