A Synthetic Technique of Settlement Control for Shield Underrun the Railroads

盾构 穿越铁路的沉降综合控制技术

The effect of underrun of hydro-power station on air erosion vibration pressure pulsation and running stability of the generating set is expounded and some measures to improve the situation are proposed from optimization design and optimization operation .

阐述了水电站 低 负荷 运行对 机组 气蚀、振动、压力脉动和运行稳定性的影响，并从优化设计和优化运行方式两个方面给出了改善 低 负荷 运行工况的措施。

The front and rear underrun protections can effectively protect passenger cars from inserting under trucks rational energy absorption characteristics can improve impact compatibility .

前、后 下部 防护装置能有效地防止轿车 钻入，合理的能量吸收特性可改善载货汽车与轿车的碰撞相容性。
