在此采用岩土工程专业软件Geo-slope对某核电站取水明渠导流堤工程进行抗震稳定性分析,运用极限平衡法,分析导流堤在地震作用下的稳定性,并给出滑弧形状以及相应的稳定安全系数。计算结果表明,导流堤按抗震III类物项进行基本抗震设计时,导流堤断面稳定安全系数均满足规范要求,设计方案是可行的。本次分析可为类似工程提供设计依据。
Geotechnical engineering software Geo-slope was used to analyze the seismic stability of the diversion dyke of a water intake of a nuclear power station. The limit equilibrium method was used to analyze the stability of the diversion dykes under earthquake action. The corresponding stable safety factor. The calculation results show that when the embankment embankment is designed for the basic aseismic design according to the Class III airstrips, the stability and safety factor of the section of the diversion embankment meet the requirements of the code, and the design scheme is feasible. This analysis can provide design basis for similar projects.
