为实现土质边坡的监测分级、提升监测设备的非冗余布设水平,先结合土质边坡稳定性影响指标的归一化取值和采用层次分析法确定的指标影响权重,构建了分区危险性评价模型;再基于边坡分区危险性系数进行了边坡危险性分级,并结合规范标准建立了与其相匹配的监测分级及设备布设数量建议;最后结合实际工程验证了该方法的可行性和可靠性.研究结果表明:1)基于土质边坡监测分级的影响指标选取相对合理;2)分区危险性评价模型可行;3)相较常规边坡监测方法,根据边坡危险性进行分级监测更符合边坡工程实际,设备的非冗余布设水平更高.研究结果可供不同类型边坡的监测作业参考.
Study on Monitoring Grading and Stability Zoning Method of Soil Slope Based on Digital Monitoring
In order to realize the monitoring grading of soil slopes and improve the level of non-redundant deployment of monitoring equipment,a zonal hazard evaluation model was constructed by combining the normalized values of the indicators affecting the stability of soil slopes and the influence weights of the indicators determined by the hierarchical analysis method.The slope hazard grading was carried out based on the zonal hazard coefficients of the slopes,and the recommendations on the monitoring grading and the number of equipment deployment were established by combining with the norms and standards to match with them.Finally,the feasibility and reliability of the method are verified with the actual project.The study shows that:1)the selection of influence indicators based on the monitoring classification of soil slopes is relatively reasonable;2)The zonal hazard evaluation model is feasible;3)Compared with the conventional slope monitoring method,the classification monitoring based on the slope hazards is more in line with the actual slope engineering,and the level of non-redundant deployment of equipment is higher.The results can be used as a reference for monitoring operations on different types of slopes.
