| 摘 要： | 以西气东输管道沿线的某黄土高边坡工程为依托,进行边坡稳定性的现场监测试验,测试边坡应力变化状态。以监测数据为基础,应用突变理论方法,建立黄土边坡坡监测预警的尖点突变模型,对具体监测数据进行滑坡超前预警的应用,通过与实际监测反映的边坡状态对比分析,验证预警模型的效果,说明尖点突变预警模型反映的边坡稳定状态改变特征与监测数据反映结果的一致性。

| Abstract: | Based on a loess high slope along west-east gas pipeline,the on-site monitoring experiment about the slope stability have been done.The stress change of the slope has been tested in this monitoring experiment.depended on the monitoring date and applied the method of catastrophe theory,a sharp point catastrophe model of monitoring and early-warning of loess slope stability was established.It also been applied to analyze monitoring date for a specific landslide stability advance warning.By compared with the r... |
