Physical model experiment on the influence of water depth on the underwater pipeline surface impacted by landslide surge
Abstract A physical model experiment of flume block landslide was used to study the influence of landslide surge impact on underwater pipeline surface under different water depths. The influence of surge impact pressure on pipelines with different water depths and the impact pressure of surge at dif...
