The results show that: the degree of deformation and yield-region will decrease as the fraction coefficients increasing; the influence of fraction coefficient f1 between clip-pieces and anchor plate is more remarkable than f2 between anchor plate and under board, the influence of f2 can be negligible.

有限元分析结果表明：随着摩擦系数的增大，锚环的变形和塑性屈服区域面积将逐渐减小；夹片与锚环之间摩擦系数f_1对锚具特性的影响要比垫板与锚环之间摩擦系数f_2所产生的影响要显著得多，后者的影响几乎可以忽略。

It studied the traditional pressure plate bolt anchoring system ,filling and drainage system,and the model of dam-side layout in the rubber dam.After repeated calculation,proposed the new pressure plate bolts anchoring component using pairs of anchor bars and connect the anchor plate and the platen with high-strength bolts,compared and analysis with the traditional pressure plate bolt anchoring system.

小 摘要：通过对现行橡胶坝设计中传统螺栓压板式锚固系统、充排水系统及坝端布置模式的研究，运用对比分析的方法，经过反复计算提出采用双锚筋及用高强螺栓连接锚固垫板和压板的新型螺栓压板式锚固构件，并与传统锚固型式进行对比分析。

Should I just be a neutral backboard, so you can bounce ideas off me?
