边坡监测和预警系统是减轻滑坡灾害的一种很有前途的方法。许多大规模的沉积物灾害造成基础设施的破坏和人命的损失。预警警报将大大有助于减轻易受斜坡和山崩危害的脆弱性。作者一直在开发监测技术,该技术使用微机电系统倾斜传感器阵列,检测脆弱斜坡的意外移动,并通知紧急警告和警告警报的发布。在这方面,确定警报阈值是非常重要的。虽然以前的研究已经调查了记录的阈值由一个引伸计,在适当的位置安装一个引伸计也是困难的。作者更喜欢倾斜传感器,并提出了一个新的阈值的倾斜角度,这是在这项研究中得到验证。这个阈值有一个有趣的相似性,以前报道的粘性模型。此外,多点监测最近出现,并允许许多传感器被部署在脆弱的斜坡,而不忽视斜坡的非正式的本地行为。利用这种新技术,可以确定脆弱边坡在位移向破坏方向发展时的详细的空间和时间变化。
Slope monitoring and early warning systems are a promising approach toward mitigating landslide-induced disasters. Many large-scale sediment disasters result in the destruction of infrastructure and loss of human life. The mitigation of vulnerability to slope and landslide hazards will benefit significantly from early warning alerts. The authors have been developing monitoring technology that uses a micro-electro-mechanical systems tilt sensor array that detects the precursory movement of vulnerable slopes and informs the issuance of emergency caution and warning alerts. In this regard, the determination of alarm thresholds is very important. Although previous studies have investigated the recording of threshold values by an extensometer which installation of an extensometer at appropriate sites is also difficult. The authors prefer tilt sensors and have proposed a novel threshold for the tilt angle, which was validated in this study. This threshold has an interesting similarity to previously reported viscous models. Additionally, multi-point monitoring has recently emerged and allows for many sensors to be deployed at vulnerable slopes without disregarding the slope’s precursory local behavior. With this new technology, the detailed spatial and temporal variation of the behavior of vulnerable slopes can be determined as the displacement proceeds toward failure.
