摘要

运动型滑坡处于蠕动变形与剧烈变形阶段之间

变形时间长、机理复杂

临灾预警难度大。介绍了典型运动型滑坡的累积位移关系曲线特征

提出了以日降雨量、日位移速率建立临灾预警线

进而设计递进式滑坡临灾预警系统的方法。结合王家坡滑坡地形地貌、剖面特征、变形信息等

建立合理的监测网络。根据获取的王家坡累积位移-时间-降雨量关系曲线

分析王家坡滑坡的变形规律。结果表明:①王家坡滑坡监测累积位移曲线随降雨呈"阶跃"特征;②当日降雨量超过25mm时

日位移速率就会显著增加到20mm/d以上;③以降雨量、日位移速率达到阈值时为Ⅲ级黄色线中心线

可以设计王家坡滑坡5级递进式滑坡临灾预警系统。

Abstract

It is difficult to perform early warning of sports landslide between the creep deformation stage and the severe deformation stage

because the deformation time is long and the mechanism is complicated.The cumulative displacement-time relationship of typical sports landslides are introduced

the precautionary line is proposed by using daily rainfall and daily displacement rate

and the progressive landslide disaster warning system is designed.Taking the Wangjiapo landslide as an example

combined with information related to landform

profile and deformation

a reasonable monitoring network is established.According to the cumulative displacement-timerainfall relation curve

the deformation of the landslide is analyzed.The results show that:（1）The accumulated displacement curve has a step characteristic with rainfall;（2）The daily displacement rate increases significantly to 20 mm/d when the daily rainfall exceeds 25 mm;（3）The disaster precautionary line of the Wangjiapo landslide is designed by using 3-level warning yellow line when the daily rainfall and daily displacement rate reach the threshold.
