无砂混凝土作反滤层的试验研究 总被引：2，自引：0，他引：2
反滤层是防止土体渗透破坏的有效措施，无砂混凝土具有良好的透水性、过滤性和稳定性。由于无砂混凝土具有自身的稳定性，用作反滤结构时不需要设置多层；还可以起到支撑作用，替代部分沟壁、井壁和挡墙等结构，可用于公路、铁路、水工建筑物中作反滤层。对无砂混凝土保护不同类型土料进行反滤试验研究，提出了无砂混凝土作反滤层的设计准则。 相似文献

High Speed Stability and Curving Performance of Longitudinally Unsymmetric Trucks with Semi-active Control 总被引：1，自引：0，他引：1
Y. Suda Associate Professor 《Vehicle System Dynamics: International Journal of Vehicle Mechanics and Mobility》1994,23(1):29-52
The possibility of improving both the dynamic stability and curving performance of railway trucks through the use of semi-active control is discussed. According to the direction of vehicle motion, the truck parameters are switched in a longitudinally asymmetric manner. Using a method of evaluation proposed here, the stability of trucks having the same steering ability was examined using linear models. A truck equipped with independently rotating wheels on the trailing axle and with unsymmetric primary suspension has the best performance. A realistic method of achieving this is proposed: using harder primary longitudinal stiffness on the trailing axle and using a primary yaw damper only on the leading, allows bidirectional operation by changing the damping force. 相似文献
