大型高速环剪实验机的开发与应用
|
摘要
日本京都大学防灾研究所的高速环剪实验机是一种为研究滑坡、泥石流而研制的科研产品,具有较高自动化处理能力。该文记述了该实验机的基本结构、实验原理和主要特点,并对该实验机的改进和开发作了介绍。该实验机经过改进后能够模拟现场应力条件,再现或者模拟滑坡滑动过程,研究滑动机理,测定相应的强度参数,研究不同条件的剪切特性,具有实际应用价值。
The large-scale and high-speed ring-shear test apparatus introduced from the disaster prevention research institute Kyoto university in Japan has upper auto-data processed ability for studying of landslide and debris flow. This paper takes improvement including apparatus parts and testing parameters to simulate the stress condition of in- situ observation and also simulate the slippage course of landslide in order to research the mechanism of landslide slippage in the form of recording the intensity parameters in different shear character situations. The method in this paper has the actual application value.
