摘要
结合GIS空间数据分析能力与极限平衡法开发了可视化的土质边坡稳定性分析系统GiSlope,介绍了边坡几何模型、外荷载与加筋结构模型、滑动面及地下水位线模型等分析模型的可视化建立过程,阐述了计算分析的设定、任意形状滑动面土条条分方法以及计算参数的确定方法。通过对几个典型实例的分析与国内外商业软件计算结果的对比,验证了系统计算的正确性和可靠性。
Combining the spatial analysis function of GIS with the limit equilibrium method,a visualization system（GiSlope） for soil slope stability analysis is developed.The visualizing establishment process of the analysis model is introduced.The setting of the analysis,slices division methods of random shape of slip surface and the method of confirming parameters are explained.Finally,several typical examples are put forward for comparing GiSlope with commercial software.The results prove that GiSlope is accurate and credible.
