dam top meaning in English

坝顶

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。
In the program , the effect of lamination placement , construction interval , elastic modulus change , thermal insulation change , surrounding temperature change , concrete creep and autogenous volume change on thermal stress are considered . and such temperature control measurement as water pipe cooling , heat preservation of the dam surface , the pouring temperature control , the overflow across the dam top during flood season can also be simulated by numerical method
该程序在编制过程中考虑了混凝土分层浇筑、施工间歇、弹模变化、绝热温升过程、环境温度的变化、混凝土徐变、自生体积变形等因素对坝体温度场及温度应力场的影响，同时也考虑了水管冷却、坝体表面保温、控制浇筑温度、施工汛期坝顶面过水等各种温控措施的数值模拟。
