查询词典 arch

Experimental research on the vibration of single slab and multi ones set in the arch ring is carried out in the first time. Slab vibration divisions along the water flow are proposed and their lists are determined. Laws of vibration distribution along water flow, across the arch ring, in time zone and frequency one are established. The most dangerous condition to slab's stability is obtained by comparing slab vibration in the different downstream depth.
