摘要 ：
本发明公开了一种宽流速多流向双向涡激振动俘能装置和方法，其中装置包括，竖直定轴、可绕定轴旋转的水平的悬臂和竖直俘能柱体。悬臂和定轴之间通过扭转弹簧连接。悬臂沿长度方向设有导轨滑块组件，上面垂直于悬臂悬挂俘能柱体，俘能柱体可以沿悬臂长度方向振动。整个装置包含悬臂绕定轴的转动自由度和俘能柱体沿悬臂长度方向的平移自由度。定轴底部装有驱动电机可以带动定轴旋转改变悬臂方向。此方案可以激发横流和顺流双向涡激振动，其俘能效率更高。同时，流速和流向发生变化时，该方案可以通过旋转定轴调整悬臂和来流之间的夹角，调整俘能柱体在横流方向上的自振频率使其和涡泄频率保持一致，从而有更宽的流速流向俘能范围。

摘要 ：
Structures crossing irregular topography features such as canyons and mountains may suffer from spatially varying ground motions due to topographic effect. In this paper, a two-dimensional substructure model of water -solid interaction in canyon site is proposed to study the effect of canyon topography on the seismic responses of water-canyon system, in which the wave radiation effect of infinite solid domains is simulated by the combined zigzag-paraxial boundary and the solid-water interaction is considered by interface conditions. Moreover, to verify the proposed substructure model, it is used to calculate the seismic responses of a V-shaped water-canyon system and a semi-circular water-canyon system under obliquely incident P-SV waves in homogeneous half space. Afterwards, we conduct the seismic analysis of water-canyon system. The results indicate that the amplification and reduction of ground motion is affected by geometric shape of canyons and water depth, and the maximum amplification of V-shaped water-canyon system can beyond an order of 200%, and the maximum amplification of semi-circular water-canyon system is less than 200%.

摘要 ：
Offshore wind power structures are subjected to complex dynamic loads in marine environment during their service. At present, the real sea conditions can be simulated to the maximum extent by the mixed test technology of boundary layer wind tunnels, wave pools and shaking tables. However, due to the high cost of test and the lack of a complete and mature combined simulation laboratory which can be operated for wind, wave and seismic loads, it is difficult to carry out such joint tests. It is advantageous to use self-developed mechanical devices to simulate marine environmental loads within the controllable errors and which is in simple operation. A series of dynamic model tests were carried out on saturated sand foundation in order to explore the feasibility of studying dynamic response of offshore wind power pile foundations through simulating marine environmental loads by simplified methods. Based on Stokes second-order wave theory and harmonic superposition method, the time history of wind, wave and current load is derived and programmed, then the wind, wave and current load on offshore fan model structure is simulated by using self-developed complex dynamic loading system. Finally, the dynamic response of single pile foundation in saturated sand under complex load is analyzed according to the test results. The test results show that the load displacement curve of single pile foundation in saturated sand is of work hardening type. The maximum pile bending moment at the peak of dynamic load increases with the increase of loading times, but the cumulative effect of bending moment caused by the change of load amplitude should be considered. The dynamic load in marine environment will cause the increase of pore pressure around the pile, but the increase of pore pressure on loading side is not obvious in comparison to that on the opposite side. The displacement change of pile body is basically in accordance with the fluctuation trend of test load and increases with load. The cumulative rate of displacement of single pile decreases with the increase of number of cycles under the long-term cyclic wind wave load. In this study, the method combining theoretical calculation of wind, wave and current load with model test of complex loading system can consider the characteristics of dynamic loads of marine environment more accurately, compared with the empirically determined cyclic load waveforms in conventional tests, the obtained response law is more in accord with actual sea conditions.

摘要 ：
Neglecting the inertial forces associated with the relative acceleration of pore fluid, this paper presents a u-p analytical solution of the dynamic impedances of a horizontally vibrating pile embedded in a saturated soil layer whose boundary region is radially inhomogeneous. To facilitate the analysis, we further divided the inhomogeneous boundary region into a set of concentric annular sub-region, and the material properties of each subregion are assumed to be constant. The impedances of radially inhomogeneous saturated soil are calculated by making use of transfer matrix method. The present solutions are compared with the existing u-w analytical solution. The influence of the shear modulus, permeability coefficient, soil porosity, pile radius and radial inhomogeneity on the errors between u-p form and u-w form are investigated. Then, the applicable range of the u-p approximation is given.

摘要 ：
Offshore structures in earthquake-prone areas are threatened by seismic and wave currents. The dynamic response of a cross-sea bridge with rectangular pier under the action of earthquake and wave is analyzed in this paper. Firstly, the main girder structure and pier structure of the sea-crossing bridge are discretized as Euler beam element and fiber element (nonlinear) by finite element method, respectively. Moreover, the waterstructure interaction is replaced by additional mass, and the soil-structure interaction is replaced by horizontal spring, horizontal damping, rotating spring and rotating damping. After that, based on the analysis of the natural vibration frequency of the structure, the influence of the interaction between the water-structure and the soil-structure stiffness on the natural vibration frequency of the structure is discussed. The effects of structure nonlinearity, soil foundation spring, soil foundation damping, hydrodynamic pressure, travelling wave and wave force on sea-crossing bridge are studied based on dynamic response analysis.
