In order to understand the seismic performance of the large complex structure with basement, the structure-pile-soil finite element model of two typical cross sections of the Tianjin Transportation Junction were established by using the ANSYS software. The elasto-plastic time history analysis was made, and the seismic responses of the whole system under the horizontal seismic load were got. Comparing the results of the seismic response with the rigid foundation model, some reasonable conclusions are drawn.

为弄清楚带有地下室大型复杂结构的抗震性能，本文针对天津站交通枢纽工程，分别取结构典型的横向及纵向剖面，应用大型通用有限元分析软件ANSYS，建立了结构－桩－土体系相互作用的有限元模型，采用动力时程分析方法，研究体系在水平地震作用下的弹塑性动力反应规律，分析结构在地震动作用下的位移和内力的分布；并与假定刚性基础周边土简化为弹簧的结构模型的计算结果进行比较，通过两种模型的地震反应的对比分析，得到了一些有益的结论。

In the meantime, the difference between a direct integration method and a modality superposition method in the nonlinear solution of large sized shaftings was also investigated. It can be shown that the use of a nonlinear method for solving the kinetics response of a higher dimensional rotor bearing system is both essential and feasible. With regard to the nonlinear kinetics problems of a rotor system the direct integration method is more effective than the modality superposition method. steam turbine, rotor, dynamics, nonlinearity

国内外先后采用非线性油膜力的数值积分方法对转子轴承系统的非线性动力学行为进行了一定研究，但主要集中在简单转子—轴承系统的研究上，在分析上主要采用的是简单离散方法，转子多被简化为刚性转子和Jeffcott转子模型，只能对简单转子—轴承系统的非线性动力学行为进行定性的分析，而对于象汽轮机组轴系这样的高

When the load smaller than the first outlet pressure adjustment valve set pressure, pilot valve Poppet head off an oil chamber, oil chamber 2 is equal to the pressure on the outlet pressure, the main valve of the sliding shaft 2 inside the cavity in the oil a rigid under the action of a small spring at the lowest position, the main valve and the valve slider protruding shoulder posed by all the valve port opens, pressure reducing valve without decompression.

当负载较小，出口压力低于先阀的调定压力时，先导阀的提动头关闭，油腔1、油腔2的压力均等于出口压力，主阀的滑轴在油腔2里面的一根刚性很小的弹簧作用下处于最低位置，主阀滑轴凸肩和阀体所构成的阀口全部打开，减压阀无减压作用。

These problems include the selection of the pile styles, the application of the composition foundation of rigid piles with soft piles together, the computation of bearing capacity and settlement, the relation between the stress radio and bearing capacity, and the application of counter-construction using in composite foundation.

In Taylor's hypothesis, material and spiritual stimulation, disciplinary and cultural management,visible and invisible environments are integrated successfully. Plenty of ideas about "social man" and "self-actualizing man" are enabling it to be "new economic man", which is sharply different from classical "economic man" in essence.
