Abstract: With a fast development of hydraulic engineering, the hydropower engineering and port waterway engineering in the middle-upper reaches of the Yangtze River, how to ensure the safety of the moored ships in the inland navigation ports under the action of landslide surge is an extremely important issue. In order to well understand the influence degrees of the landslide surge impacting the inland navigation ports, model test researches were carried out by taking 3 000 t deck barges moored in the Jiannan Tuokou port as a research object. On the basis of analyses and studies of the impact factors of the mooring force and the impact energy by the action of the landslide surge, the change law of the mooring force and the impact energy was found out from the surge wave height and water depth. According to the specifications and test data, the empirical formula for the mooring force and impact energy was given by a regression analysis. Ascertaining the influence degrees of the landslide surge impacting the inland navigation port, some countermeasures and suggestions were put forward for the port operation and management. The research results show that the findings have a high practical value and can be applied to the forecast and prevention of the landslide surge impacts on the navigation ports located at mountain rivers.
