首先介绍了3种在自组织作用下的反映斜坡物质能量耗散普适性过程的沙堆模型实验,以及托卡马克等离子体试验.实验表明,当沙堆由非均匀颗粒组成时呈现SOC现象;托卡马克等离子体当约束条件减弱时具有SOC的一些特性.然后通过沙石材料土工性质的测试和堆积结构模拟分析,得出SOC主要由系统的组构特征确定的结论.最后在SOC的概念框架下讨论了斜坡重力作用灾害的机理研究、预测预报以及防治工程设计等问题.
First of all, three kinds of sand-pile model experiments that reflect the general process of energy dissipation of slope material and the tokamak plasma test under self-organization are introduced. The experiment shows that the SOC phenomenon appears when the sand pile consists of inhomogeneous particles . The Tokamak plasma has some characteristics of SOC when the restraint conditions are weakened.And then, through the test of geotechnical properties of sandstone material and simulation analysis of the accumulation structure, the conclusion that SOC is mainly determined by the structural characteristics of the system is obtained.Finally, Under the conceptual framework, the mechanism research, forecast and prevention and control engineering design of slope gravity are discussed.
