岩石力学问题的集成分析法

1 INTRODUCTION Increasing requirements of economics results in that more and more rock engineering is or will be constructed in worse strata and the size and scale are getting larger and larger. For examples，the permanent shiplock of Three Gorges Project，China is double channel with five stages. The main powerhouse of Xiluodu hydraulic power station，China，is 7530 300 m in size，which is far outside of the existing standard analysis methods and precedent type analysis. There is thermal mechanical problem occ...

INTEGRATED ANALYSIS APPROACHES TO ROCK MECHANICS PROBLEMS

In order to effectively cope with exponent increase of the complexity faced to the rock mechanics analysis problems and the large incompatibility existing between the information level required to model the rock mass and engineering and our obtainable information level at hand,the integrated approaches with intelligent characters are proposed. Many previous standard methods,such as precedent type analysis,rock classification,analytic method stress-based,basic numerical methods (BEM,FEM,DEM,hybrid),and their extended numerical methods (fully coupled) to be developed,can be selected respectively or integrated accordingly. It is alternative to develop basic/fully integrated system,and internet-based approaches. These novel methods can also be selected or integrated each other or with the standard methods to perform rock mechanics analysis. Some key techniques to develop these alternative methods are discussed. It may focus in future on developing fully integrated systems and internet-based approaches. Developing an environmental,virtual facility/space shall be firstly done for this collaborative research on internet.
