| Abstract: | In view of test model,test materials,test equipment and testing content,one test plan of debris flow on slope of engineering slag was established.Meanwhile,the test schedule was clarified as that the rainfall duration is 16 - 18 hours,of which 0～13 hours was the previous rainfall stage and rainfall intensity was 6.8 mm/10min completed in 4 times.And each rainfall and pause durations were 1 hour and 2 hours separately.It was the stage of the heavy rainfall of short duration after 13 hours during which rainfall intensity was 16.7 mm/10min.The physical and mechanical properties of the formation processes of debris flow on slope of engineering slag were demonstrated through the analysis of the change of moisture content, pore water pressure and surface displacement elevation with rainfall duration of engineering slag on slope. |
