由于施工现场的复杂性以及不确定性，边坡实际开挖形态与设计开挖形态往往会存在偏差，为了规避因偏差导致边坡稳定性降低从而留下的安全隐患，进行边坡开挖质量分析与稳定性分析研究。以全容高速某段岩质高边坡为研究对象，针对其在开挖过程中坡面出现的岩块滑落现象，采用无人机倾斜摄影采集边坡多视角影像，结合三维重建方法构建边坡三维模型，在此基础上通过断面法进行边坡开挖质量分析，并采用数值模拟方法进行边坡稳定性分析。分析结果表明：①边坡存在两处缺陷，分别体现为局部凹陷和局部坡率偏高；②边坡整体稳定性达标，但因3组节理裂隙存在，近坡面部分仍可能出现碎石滑落。为防止坡面岩体再度剥落，应加装主动防护网系统进行坡面岩体加固。可见基于倾斜摄影重建的边坡三维模型，能同时为开挖质量分析和稳定性分析提供可靠的空间数据支持，在此基础上实现了对开挖边坡的多维度分析，具有较强的实际应用价值。

Due to the complexity and uncertainty of the construction site, there is often a deviation between the actual excavation form of the slope and the designed excavation form. In order to avoid the potential safety hazards caused by the reduced stability of the slope due to the deviation, the slope excavation quality analysis and stability analysis were studied. A section of the high rock slope of Quanrong Expressway was taken as the research object. In view of the rock block sliding on the slope surface during the excavation process, the multi-view images of the slope were collected by unmanned aerial vehicle oblique photography, and the three-dimensional model of the slope was constructed by combining the three-dimensional reconstruction method. On this basis, the slope excavation quality analysis was carried out by the cross-section method, and the slope stability analysis was carried out by numerical simulation method. The analysis results show these as follows. There are two defects in the slope, which are manifested as local depression and local high slope rate. The overall stability of the slope meets the standard, but due to the existence of three groups of joints and fissures, gravel sliding may still occur near the slope surface. In order to prevent the slope rock from peeling off again, an active protection net system should be installed to reinforce the slope rock mass. It can be seen that the three-dimensional slope model reconstructed based on oblique photography can provide reliable spatial data support for excavation quality analysis and stability analysis at the same time. On this basis, it realizes the multi-dimensional analysis of the excavated slope and has strong practical application value.
