生态护坡材料本构关系的研究

Study on Constitutive Relation for Eco-material Used to Slope Protection

基于生态护坡材料的室内试验成果 ,分别利用双曲线和二次抛物线模型模拟其应力～应变关系 ,并给出了相应的模型试验参数。结果表明 :材料的应力～应变关系用双曲线模型模拟误差较大 ,而用抛物线模型模拟则比较理想。对不同水泥掺量和龄期的材料 。

Based on the testing results in laboratory, the stress strain responses of the eco material are simulated by the hyperbolic and parabolic models, and the testing parameters of models are given. The results show that the hyperbolic model to analyze the stress strain relationship of the eco material has a larger error, but the parabolic model to describe its stress strain response is very reasonable. A uniform constitutive relation can be used to describe the stress strain relationship of the eco materials with different cement added and coagulate time.
