Comprehensive Risk Analysis of Dongting Lake Dike Engineering
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%.
