摘要： 针对传统边坡体建模精确度不高的问题，引入多约束离散平滑插值(discrete smooth interpolation，DSI)算法，通过改进团队自主研发的三维数值分析系统GeoSMA-3D，获得多约束DSI拟合建模新模块.利用原始钻孔和物探数据辅以离散结构面信息对边坡整体进行插值，通过互异的约束条件对不同特征的地质对象进行标定，进而采用改进的修正函数对边坡体进行拟合建模，通过高精度的三维边坡体模型获取结构面信息并进行聚类分组.结果表明:该方法提高了离散介质岩体分析的准确性，具有较好的理论意义及工程应用价值.

Abstract: Aiming at overcoming the low accuracy of traditional slope modeling， a new multi-constraint DSI fitting modeling module was established by introducing multi-constraint discrete smooth interpolation(DSI)algorithm in improving the self-developed 3D numerical analysis system GeoSMA-3D. Firstly， the original drilling and geophysical data were used to interpolate the whole slope with discrete structural plane information， then the geological objects with different characteristics were calibrated through different constraints， and then the slope body is fitted by the improved correction function. Finally， the structural plane information was obtained through the high-precision three-dimensional slope model and the clustering group was carried out. The results show that the method improves the accuracy of discrete rock mass analysis with good theoretical significance and engineering application value.
