摘要: 水利工程高邊坡的穩定分析對于邊坡支護措施的設計具有重要意義,二維邊坡穩定分析無法考慮坡面和巖層的空間變化,不能滿足高邊坡穩定分析的精度要求。充分考慮邊坡體地形、地質的空間形態變化,通過建立基于地形、地質精細模型的三維邊坡開挖模型,采用基于強度折減法的三維有限元軟件,實現對水利工程高邊坡三維開挖的穩定分析。以西藏某水利工程為例,分別通過二維邊坡分析和三維邊坡分析計算在不同工況下的穩定系數和滑動帶,結果表明,與二維分析相比,三維邊坡穩定分析得到的結果更加符合工程實際。

Abstract: High slope stability analysis of water project is very important for the design of slope supporting. Because spatial variation of surface and strata cannot be considered, 2D slope stability analysis cannot meet the accuracy requirements. In this paper, the spatial variation of terrain and geology of slope was fully considered. By establishing a 3D slope excavation model based on topographic and geological fine models and using the 3D finite element software based on strength reduction method, the 3D high slope stability analysis of water project was realized. Taking a water project in Tibet as an example, the safety factor and sliding zone under different conditions of 2D and 3D slopes were calculated respectively. The results show that comparing with 2D analysis, the analysis of 3D is more consistent with engineering practice.
Key words: high slope; slope stability analysis; 3D refined model; strength reduction method; water project
