三峡永久船闸高边坡岩体长期变形与稳定研究

Long-Term Deformation and Stability of High Rock Slope at Three Gorges Shiplock

三峡工程永久船闸高边坡岩体开挖后的长期变形与持续稳定控制是工程的关键技术之一,为此,进行的研究工作包括一些非常规岩石力学试验以及对边坡岩体外露表面和浅部岩帮进行变形监测,进而采用DEM、DDA等多种方法,按三期空间问题进行计算分析。一些重要的结论和建议对设计与施工都是很有帮助的。

The long term deformation and stability of high rock slopes at the Three Gorges shiplock is among the key technical issues for the Three Gorges project. The investigation work completed for it includes 3-D viscous elasto-plastic analysis by FEM, DEM, DDA and FLAG numerical studies, etc. , as well as conventional geotechnical tests and in-situ deformation monitoring. Important conclusions and recommendations made herein would be helpful to the design and construction of the project.
