摘要
根据长江科学院 2 0多年来地质力学模型试验的经验和国内外的发展现状 ,分别从相似原理、模型材料选择、关键模拟技术和在不同工程地质问题中的应用等方面介绍了地质力学模型试验技术的特点及发展趋势。认为地质力学模型试验技术应向深度 (即模拟和量测技术 )和广度方向发展 ,在发现新的力学机理和验证数学模型等方面有广泛的应用前景。
In this paper,according to over 20 years experience on geomechanic model experiments of Yangtze River Scientific Reasearch Institute(YRSRI) and developmental status of this model at home and abroad,the characteristics and developmental tendency of geomechanic model test techniques are introduced from some aspects such as the criteria of similarity,model material selection,key simulation techniques and applications to different geological problems.It is considered that geomechanic model test techniques should make progresses in depth,namly,simulation and measurement technique,and in wide scope.It still has broad application prospects in discovering new mechanics mechanism,verifying mathematics model and so on.
