Abstract:Considering the conditions of hydrology, engineering geology, construction, influence on surrounding existing buildings, as well as the operation management, land acquisition input and other aspects of the sluice, this paper analyzes and compares the feasible site schemes for the demolition and reconstruction of Dongliu new sluice comprehensively, and verifies them through the hydraulic model test. The selection of the new gate site is in line with the concept of adhering to the people-oriented, human-water harmony, and highlights the environmental and social benefits, which can provide reference value for the site selection of similar sluice projects.
