Applying the multigrid method the air bearing pressure of pico slider(30%,1.
0mm,飞高7nm)的气膜承载压强,相比较单网格方法,多重网格方法求解性能提高显著。
Debonding of interface between steel strand and grout is the dominant failure mode of conventional prestressed anchor cable,in order to avoid this failure mode,the bulb anchor of structural engineering is modified and used for geotechnical anchorage project to enhance the bearing strength of embedded section.
普通预应力锚索的常见破坏模式是钢绞线与注浆体脱粘,为防止该类破坏模式的发生并增强内锚固段的承载强度,将结构工程的压花锚进行改进并应用到岩土锚固工程,设计了8种不同配合比的水泥基注浆体,将普通锚、压花锚锚固在中风化砂岩中,通过抗拔试验获得了岩锚的荷载~位移全过程曲线。
The influence of the lateral compression and bedplate size on the compressive strengthand the cracking load is studied.
文章根据１５个混凝土双向局部承压试件的实验结果，分析了侧向压力、垫板尺寸对混凝土双向局部承压强度和抗裂强度的影响，基于试验结果，提出了一些建设。
