摘要
对高铁通过某铁路沿线附近人工湖蓄水后的安全分析,利用渗流强度理论,采用有限单元法计算,探讨了高铁通过某路基拟地震烈度和拟震动反应谱对人工湖大坝的影响,结果表明:拟地震烈度和拟震动反应谱频率影响下人工湖蓄水后,大坝安全系数和位移变形等均在允许范围内,人工湖稳定是安全的。本文的分析对其他工程遇到类似问题具有一定参考价值。
The safety analysis of high speed rail passing through an artificial lake near a railway line is carried out by using the seepage strength theory and the finite element method,the influence of the quasi-seismic intensity and quasi-vibration response spectrum of high-speed rail on artificial lake are discussed,the results show:pseudo earthquake intensity and pseudo shock response frequency influence the storage of artificial lake after artificial lake storage,the safety factor, displacement and deformation of the dam are all within the allowable range,the stability of artificial lake dam is safe.The analysis of this paper has certain reference value for other projects encountered similar problems.
