Abstract

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.
