水平旋转耦合振动下地基惯性及刚度的研究

On the Inertia Properties and Rigidity of Base Soils under Vibration of Sliding and Rotation

改变过去动力机械基础在水平旋转振动作用下,不考虑土的惯性作用的作法,将待求参量由3个变为4个(称为动力分析中的四参数模型).应用这个新模型进行分析,可获得更符合实际的计算结果.

Unlike before, the authors have proved that the inertia effect of base soil must be considered and the inertia action of soils is very evident by a number of tests. And then, the number of the parameter to be determined shall change from 3 to 4. Here, the model is.refered to as 4 parameter model. Only using the new model, the results of dynamic computation could be conformable to practice well.
