Implementation Strategy and Flood Risk Analysis for Construction Diversion of Huangshipan Reservoir
The construction of Huangshipan Reservoir has a long flood season,high upstream pressure,and a high risk of overflow from the earth rock dam.Based on the engineering geological and hydro meteorological conditions of the construction reservoir area,this article proposes a construction diversion plan for the first phase cofferdam to use earth rock cofferdam,and the second phase cofferdam to use longitudinal concrete cofferdam and upstream and downstream transverse earth rock cofferdam.At the same time,it conducts a risk assessment during the flood season and proposes reasonable construction flood safety measures and emergency plans,providing safety support for the later construction of the reservoir.
