Considering the problem that different technical schemes adopted for important technical problems involved in different stages of Guangxi and domestic ship locks cause the different utilization effects of inland navigation resources，this paper uses the method of summary and analysis to study the relationship between the technical schemes selected by Guangxi’s ship locks at different stages of reform and opening up and the utilization effects of inland navigation resources from a technical point of view. Then the paper sorts out important technical problems affecting the full utilization of inland navigation resources in the early planning stage，construction stage and operation stage，and puts forward plans or views to solve important technical problems. The results show that to make full use of inland navigation resources，we must systematically solve the important technical problems of the lock in the early planning stage，construction stage and operation stage.
