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.

Key words： slope engineering 3D laser scan data process quality evaluation excavation
