- Abstract:
- The Lamaxi channel is a tributary of the Liusha stream.The different scale debris flows ever occured along these gullies in history.The gullies are affluent in the Quaternary sediments.The debris flow induced by heavy rainstorms is still possible.To ensure the safety of the bridge operation,based on the investigation at the scene,according to the study of the home and abroad,the authors analyzed the formation and the dynamic characteristics of the debris flow with the characteristics of the Lamaxi channel drainage area.Through calculating the probability of different design of the debris flow velocity,peak flow,a one-time total volume of solid matter of the debris flow,the bridge project facilities are considered by the service life of 100 years.The loose source of the Lamaxi channel drainage area may start instability in the event of a return period of 100 years of heavy rainfall circumstances.This has a certain influence to the safety of the bridge operation.This study to guarantee the safety of the bridge has an important practical significance.
