本文介绍了一种创新的声发射地下斜坡位移监测系统的性能安装在一个大型的沿海滑坡复杂的平崖，北约克郡，英格兰东北部。悬崖不稳定性是由一条进出道路的重复变形所指示的，该道路为大约50座房屋的定居点服务。作为广泛的地面调查的一部分，在一个标准倾斜仪附近安装了一个可以量化声发射的传感器，此后一直在对声发射进行连续监测。声学传感器检测到斜坡变形的周期，并通过倾斜仪的手动测量进行确认。性能证明使用时间序列的声学测量与地面变形和触发降雨事件相比。
This paper describes the performance of an innovative acoustic emission subsurface slope displacement monitoring system installed in a large coastal landslide complex at Flat Cliffs, North Yorkshire, northeast England. Cliff instability is indicated by repeat deformation of an access road that serves a settlement of about 50 houses. As part of an extensive ground investigation, a sensor that can quantify acoustic emission was installed adjacent to a standard inclinometer, and continuous monitoring of acoustic emission has since taken place. The acoustic sensor has detected periods of slope deformation that are confirmed by manual surveys of the inclinometer. Performance is demonstrated using time series of acoustic measurements compared with ground deformations and triggering rainfall events.
