Comprehensive Risk Analysis of Dongting Lake Dike Engineering

Abstract:

Comprehensive risk analysis mode including overtopping risk, slide instability risk and seepage risk has been established. Chaishanhu section of Lannihu polder which is a important polder of Dongting lake as an example, the result showed: overtopping risk rate is 0.23%, if consider the influence of wave run-up and wind increase-water-output, it will be 0.84%; Seepage risk rate is 1.22%, slide instability risk rate is 0.94%. Comprehensive risk rate, when not consider the effects of wave run-up and wind increase-water-output for 2.39%; If consider the impact, it is 3.00%.
