most landslides was recoursed on old ones with lots of dimensions and forms on conditions of the flows that incised the feet and the rainfalls that infiltrated. We chose a relatively stabilized slope and inspired it to re slide by artificial rainfall and observed the process

analysed and described the phenomena such as slide

glide and collapse that happened in the experiment. Some indoors experiments about soil mechanics were processed and some significant conclusions and optional parameter were acquired.
