摘　　要：本文探索三维激光扫描技术在某特大桥斜坡岩体完整性分析中的应用,通过获取的测绘信息,配合野外结构面产状测量、地质调绘、钻探资料分析,建立了斜坡岩体结构三维结构面网络模型,为数值模拟分析打下基础,为斜坡岩体完整性分析、边坡稳定性评价提供可靠依据,为同类工程提供技术借鉴。This paper explores the application of 3 D laser scanning technology in the analysis of rock mass integrity of a bridge slope.Base on surveying and mapping data,combined with occurrence of structure plane,geological mapping and drilling data analysis,a model of three-dimensional structural plane of slope rock mass is established.The model can be a foundation for numerical simulation analysis,and provides a reliable basis for slope rock integrity analysis and slope stability evaluation,and also technical reference for similar projects.
