摘要水利工程边坡开挖通常存在开挖面大、周期紧、质量要求高的特点。通过分析传统边坡开挖质量评价方法及问题，提出采用三维激光扫描技术对边坡开挖质量进行评价的手段。采用随机采样一致性算法、布尔莎–沃尔夫模型等算法建立高效的边坡开挖数据采集、处理流程；通过对边坡数据的特点分析，采用关系数据库建立基于B树及其拓展结构的海量点云数据存储与管理机制；根据边坡评价的特点提出基于开挖剖面和基于开挖平面的边坡质量评价方法。通过实际工程应用证明该方法实现开挖面质量的快速判别与控制，可极大提高边坡开挖质量控制的工作效率和信息化水平。

Abstract：Hydraulic slope excavation usually have some characteristics such as huge face and tight period，high quality requirements and so on. The problems of traditional slope excavation evaluation method was analyzed，and then a three-dimensional laser scanning technology method for the slope excavation quality evaluation was presented. By using a random sample consensus algorithm，Bursa-Wolf models and other efficient algorithms to establish a method for slope excavation data acquisition，process flow. By analyzing the characteristics of the slope data，the point cloud data storage and management mechanism by implement relational databases based on B-tree and its expansion structure were established. Then according to the characteristics of slope evaluation excavation method，two evaluation methods were proposed：cross-sectional quality evaluation and excavation plane quality evaluation. The practical application proves that this method can rapidly evaluate and control the excavation quality，which can greatly improves the quality control excavation of efficiency and the level of information.
