Propagation of vibration wave in cylindrical shell with sinusoidally perturbed wall
波紋管殼結(jié)構(gòu)中振動(dòng)波的傳播
With the input of a vibration acceleration history of subway train , a full dynamic analysis of soil - pile - structure is carried out . the propagation of vibration wave on the ground and vibration responses of the huge platform and the storied buildings are analyzed . some conclusions are drawn as follows : ( 1 ) with the increase of the distance to the vibration source , vibration intensity of the ground decreases ; ( 2 ) the vibration intensity of the ground in vertical direction is slightly larger than that in horizontal direction ; ( 3 ) with the increase of the distance to the vibration source , the situation that the vibration intensity of each building in horizontal direction is maximum at highest and lowest story whereas minimum at the middle story changes gradually to that decreasing with the height of building ; ( 4 ) in vertical direction , the vibration velocities and accelerations at the end points of each story of a building are the nominal identical , which indicates that the vertical vibration of them is unanimous ; ( 5 ) the vibration intensity in vertical direction of a building is larger than that in horizontal direction ; ( 6 ) increasing of the elasticity of track is an effective way to abate vibration of ground and buildings
本文以北京地鐵八王墳車輛段地上超大結(jié)構(gòu)(車輛段大平臺(tái)及其上的小區(qū)樓房)及其地基基礎(chǔ)為研究對(duì)象，在研究和分析有關(guān)資料的基礎(chǔ)上，用快速拉格朗日有限差分法軟件flac建立了二維數(shù)值分析模型，并以列車振動(dòng)加速度時(shí)程作為模型輸入，進(jìn)行了地基?樁基礎(chǔ)?地上結(jié)構(gòu)的整體動(dòng)力學(xué)分析，分析了地鐵列車運(yùn)行產(chǎn)生的振動(dòng)在地面的傳播規(guī)律及其對(duì)地上結(jié)構(gòu)的影響，得到了如下結(jié)論： ( 1 )隨著與地鐵線路距離的增大，地面的振動(dòng)強(qiáng)度有減小的趨勢(shì)； ( 2 )地面豎直方向的振動(dòng)強(qiáng)度較之水平方向的略大； ( 3 )隨著與振源距離的增大，在水平方向上，地上各幢樓房的振動(dòng)強(qiáng)度由底層和頂層的最大、中間層的最小逐漸過渡到沿樓層增高而減??； ( 4 )在豎直方向上，每幢樓各層端點(diǎn)的振動(dòng)速度、加速度完全相同，表明樓房各層在豎直方向上的運(yùn)動(dòng)狀態(tài)一致； ( 5 )各幢樓房豎直方向的振動(dòng)強(qiáng)度比水平方向的大； ( 6 )增加軌道彈性是減輕地面和地上建筑振動(dòng)的有效途徑。
