1)  pier
墩体
1.
Supercritical flow over a rectangular splitlitter pier behind which air can be drawn is researched by means of regression analysis and model test at medium and low Froude number.
通过试验得到急流飞越而过流态下,墩上游无因次水深及墩体阻力系数分别与设墩处水流收缩比、墩高比和控制断面Fr之间的变化关系;墩上游和墩体壁压分布,论证了墩体在墩后充分通气时产生空化的可能性。
2)  rigidity of pier
墩体刚度
1.
Some new ideas such as the critical rigidity of pier, the critical height of pier and the critical rigidity ratio of beam to pier are put forward in the paper.
以 3孔简支梁为对象 ,建立计算模型 ,从体系的自振特性和车振的特性分析墩体刚度和质量变化对梁体振动的影响规律。
