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.
