| 摘 要： | 根据模型试验相似比尺和桩土间应力协调要求,用机制砂、河砂、水泥、石粉等配置了40组(每组6个)低强度、低弹性模量的圆柱形微混凝土相似材料试件.测试结果表明:微混凝土具有和原型混凝土大致相同的应力应变阶段和破坏模式,可以模拟原型结构的力学行为和变形、破坏特征.砂率和石粉取代率不同时,微混凝土试件的轴压强度和弹性模量在较大...

| Abstract: | Considering the similitude ratio of model test and the stress coordination between piles and soil, 40 groups(there are 6 specimens in a group)cylindrical model concrete specimens were made of mechine-made sand,river sand,cement,stone powder and etc.These specimens have low-strength and low-elastic modulus.The tests show that the model concrete has similar stress-strain curves and failure modes to the prototype.So the model concrete can be used to simulate the elastic and elasto-plastic deformation of the pr... |
