DEVELOPMENT AND STUDY OF STABILITY ANALYSIS SYSTEM OF SLOPE BLOCKS
摘要: 提出了复杂形态块体几何建模的切割法, 在此基础上, 对石根华等人提出的块体理论作了改进和完善。并基于Windows操作平台, 开发了一套实用方便、实用的边坡岩体块体稳定性分析系统。经大量的实例 (例如三峡工程船闸高边坡 )检验结果表明, 该系统可以作为对边坡中复杂形状块体稳定性进行现场快速评价的实用工具。Abstract: Some new theory and methods for development of slope rock block stability analysis system are presented in this paper. Being different from others, in the theory a cutting method is used to set up a block model by which the problem of complicated geometry shapes, such as hexahedron blocks can be solved. Theoretically, this method can be generally used for evaluating the stability of wedge-blocks with arbitrary geometric shapes. A software package based on above theory has been developed in the environment of Windows 3.x and Windows 95. As a typical example, the new theory and software have been applied to stability analysis of wedge slope at shiplock high slopes in Three-Gorges Project, the far hydropower station project in the world. It provides an efficient tool for quick judgment of unstable blocks, and ensure the safety of construction.
