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 本文以北京地铁八王坟车辆段地上超大结构(车辆段大平台及其上的小区楼房)及其地基基础为研究对象，在研究和分析有关资料的基础上，用快速拉格朗日有限差分法软件flac建立了二维数值分析模型，并以列车振动加速度时程作为模型输入，进行了地基?桩基础?地上结构的整体动力学分析，分析了地铁列车运行产生的振动在地面的传播规律及其对地上结构的影响，得到了如下结论： ( 1 )随着与地铁线路距离的增大，地面的振动强度有减小的趋势； ( 2 )地面竖直方向的振动强度较之水平方向的略大； ( 3 )随着与振源距离的增大，在水平方向上，地上各幢楼房的振动强度由底层和顶层的最大、中间层的最小逐渐过渡到沿楼层增高而减小； ( 4 )在竖直方向上，每幢楼各层端点的振动速度、加速度完全相同，表明楼房各层在竖直方向上的运动状态一致； ( 5 )各幢楼房竖直方向的振动强度比水平方向的大； ( 6 )增加轨道弹性是减轻地面和地上建筑振动的有效途径。
Several opinions are given on the development and utilization of chinas iron ore resources which are : ( 1 ) it is necessary to make use of foreign resources ; ( 2 ) to keep the internal ore production at a certain scale , new mine construction should be speeded up ; ( 3 ) the management of locally runned mine should be strengthened ; ( 4 ) the load of iron mine enterprises should be reduced so as to help the existing iron ore mines get out of loss and difficulties 对我国铁矿资源开发利用提出了几点看法：一是利用国外资源是必要的；二是国内矿石产量要保持一定规模，必须加快新矿建设；三是加强对地方办矿的管理；四是减轻铁矿企业负担，帮助现有铁矿山扭亏解困。
Chinese peoples treasure of family values perhaps can help mitigate stress from work . dr siu urges managers to pay more attention to family life . this is because although managers may encounter heavy workload or work long hours , the joy of having a satisfying family life may palliate work stress , she believes 萧博士又认为中国人的家庭观念可能是减轻工作压力的因素，员工在工馀应多著重家庭生活，员工虽在工作岗位工作量高或工作时数长，但回到家中感到家庭暖所带来的生活满足感，可抵消工作压力负面的影。
