Evolution Process and Impact Analysis of the Dam-break Flood of Baihuatan Hydropower Station Based on HEC-RAS by JIANG Linjie, FU Chenghua, CHENG Xinyu, LIU Jian

“…Once the reservoir is destroyed,it will bring huge damage to peoples lives and regional economic development.This paper extracts the topographic information of the upstream and downstream of Baihuatan Hydropower Station by Google Earth and Arc-GIS,establishes a numerical analysis model of the river channel through HEC-RAS based on the 1∶1 000 topographic map of the hub,calculates and analyzes the evolution process and the scope of impact of dam-break flood under nine schemes,and clearly defines the submerged scope and transfer route.The results show that:The flow of the breach depends on the width of the breach.During the course of the dam-break flood,with the continuation of the flood into the reservoir,the peak flow of the downstream sections decreases slightly;The greater the flood into the reservoir is,the earlier the peak flow of downstream sections occurs;Guoyushe,Shihua Village,Caiyuanzi,and Anning Village will be flooded to a certain extent.The analysis results provide a scientific basis for the safe operation of power stations and emergency management of flood control,and a reference for the research of similar gate dam projects.…”

PRIMARY RESONANCE ANALYSIS OF ARM SYSTEM UNDER BOUNDED NARROW⁃BAND EXCITATION by YANG ZhiAn, MAN ZhiJun, LIU WenYang

“…By using multi⁃scales method,the first primary resonance of the human arm and vibration mechanical coupling system under random narrow⁃band excitation was analyzed,and the two⁃degree⁃of⁃freedom nonlinear dynamic equation of the arm system was established.The first primary resonance amplitude frequency response equation and Ito stochastic differential equation of the system were solved in turn.In order to study the distribution law of variables under random vibration,the approximate expressions of the expectation and mean square value of the first primary resonance random mean square response were calculated using the moment estimation method.The influence of the parameters of the human arm system on the primary resonance was obtained through numerical analysis.The results show that the mean square response curves of the first primary resonance have the same topological structure as their amplitude⁃frequency response curves,and the mean square value of the primary resonance amplitudes and the resonance region increase with the increase of the amplitude of the external excitation,while the increase of the system damping will reduce the mean square value and the resonance region.The change of nonlinear stiffness coefficient has little effect on the system.…”
