Abstract:The reservoir area of a newly-built reservoir project covers a large area and has a long construction period. During the construction period, it is necessary to ensure the safe flood control of the reservoir itself, various buildings and structures in the reservoir area and downstream, as well as the safety of the people. During the construction of the reservoir, it is restricted by various factors, resulting in changes in the reservoir flood control plan compared with the original design plan. Therefore, it is necessary to attach great importance to construction flood control, make reasonable planning, and pay more attention to dynamic adjustment to ensure the safety of flood control during the construction period.
