摘要褐蘑菇产自内蒙和冀北坝上高原，将它南移下坝进行人工栽培是本研究的目的。 - Contracted with the calculations of dam in rigid foundation , the frequencies are lesson and periods of dam are lengthened because of elastic restraint of foundation . and under earthquake load , the maximum displacement of dam top is larger
与刚性地基下坝体计算结果相比，由于地基的弹性约束作用，坝体的自振频率降低，周期延长；且在地震荷载作用下，坝顶最大动位移增大。 - Finally , niutoushan double - curvature arch dam was modeled and 3 - d fem simulation analysis was performed , so as to find out the integral safety factor and the stress and displacement patterns of dam and its foundation under different load combination
最后，对牛头山水电站双曲拱坝进行了有限元建模和三维非线性有限元仿真分析，计算分析了各种情况下坝体和基岩的应力位移规律，对大坝的整体安全度进行了综合评判。 - As for dam ' s dynamic properties in condition of elastic foundation , author uses mapping infinite element , which can reflect displacement ' s property of diminishing in semi - infinite materials . through exchanging data between three analytic software - matlab , ansys , fortran , dynamic properties of dam is computed in condition of elastic foundation . and then the dynamic displacement curve is obtained under the load of earthquake with the method of newmark - b
对于弹性地基情况下坝体的动力特性，作者采用了能够反映半无限域介质中位移衰减特性的映射无限元，通过matlab 、 ansys 、 fortran三种计算软件之间数据交换得出了弹性地基下坝体的动力特性，并通过自编newmark -法程序计算了坝体在地震荷载作用下动位移响应。 - The study consists of construction technologies of rock - fill filling of concrete facing rock - fill dam in negative temperature condition , manufacture and fill of cushion layger , exceedingly frost - resisting property of concrete facing and the protection of concrete facing in winter etc . these technologies have been come up to advanced domestic standards and some gaps in the fields of same technology has been filled in
