The construction quality of high slope excavation is the foundation of high slope construction quality.However rare research on the part of the domestic scholars, the author take HuiQing expressway as an example, the unmanned aerial vehicle low photography technique is applied to the quality of the high slope excavation construction intelligent management, and gives the corresponding intelligent management solutions, design the intelligent management of high slope excavation construction process, and analyze the management effect evaluation.The results show that the intelligent management scheme is helpful to improve the management efficiency, and provides a new idea for the management of future high slope. Which can be used for reference by other similar high slope project excavation quality management.
