The Shielding Effect of Multi-Pile Structures on Ice Force     

史庆增  黄焱宋安 《中国海洋工程》2004,18(2):197-206

The shielding effect of the front pile-row on the ice force acting on the hack pile-row is studied by ice force model tests. In the tests, the front pile-row is designed to model jacket legs and the hack pile-row to model the water resisting pipe-phalanx within the jacket. The shielding factor for ice force corresponding to different conditions are given in this paper. The research indicates that there are many factors, including the longitudinal and lateral spacing between the front and hack pile-row, ice attacking angle and the ratio of pile diameter to ice thickness, that influence the shielding effect on ice force.  相似文献

Cumulative Deformation of Soft Clay Under Cyclic Loading   总被引：2，自引：1，他引：2  

Yan Shuwang Yan Chi Zhang Jianguo Professor  Tianjin University  Tianjin Lecturer  Tianjin University  Tianjin 《中国海洋工程》1993,(3)

Reconstituted specimens are prepared by means of vacuum preloading. Both static and cyclic triaxial tests are carried out, with the specimens consolidated under different principal stress ratios. A finite element method is put forward for calculating the cumulative deformation of soft clay under cyclic loading.  相似文献   

Analysis on Motion and Cable Dynamic Tension for An ALT-Tanker System     

李红霞  唐友刚  刘利琴  张若瑜 《中国海洋工程》2009,23(2):355-366

A two-degree freedom model for an ALT-tanker system is established corresponding to the pitch of the ALT and the surge of the tanker.Tension in the mooring cable between the ALT and the tanker is represented by an unsymmetrical,piecewise-nonlinear function.Wave load on the tower is evaluated by use of the Morison equation.The first order wave load acting on the tanker is calculated by the linear diffraction theory based on the 2-D Helmholtz equation,and the near field approach of Pinkster is used to evaluate the second order drift force.The dynamic equation of motion is established based on the principle of D'lembert.Dynamic response and cable tension of a mooring system composed of an 88.4 m ALT and a 100000 t grade tanker are calculated.The influence of wave frequency,wave excitation amplitude,wind and current force on ALT-tanker motion and cable tension is discussed.  相似文献

A Three-Dimensional Nearshore Hydrodynamic Model with Depth-Dependent Radiation Stresses   总被引：2，自引：0，他引：2  

吴相忠  张庆河 《中国海洋工程》2009,23(2):291-302

For the simulation of the three-dimensional (3D) nearshore circulation,a 3D hydrodynamic model is developed by taking into account the depth-dependent radiation stresses.Expressions for depth-depeedent radiation stresses in the Cartsian coordinates are introduced on the basis of the linear wave theory,and then vertical variations of depth-dependent radiation stresses are discussed.The 3D hydrodynamic model of EICIRC (Eulerian-Lagrangian CIRCulation) is extended by adding the terms of the depth-dependent or depth-averaged radiation stresses in the momentum equations.The wave set-up,set-down and undertow are simulated by the extended ELCIRC model based on the wave fields provided by the experiment or the REF/DIF wave model.The simulated results with the depth-dependent and depth-averaged radiation stresses both show good agreement with the experimental data for wave set-up and set-down.The undertow profiles predicted by the model with the depth-dependent radiation stresses are also consistent with the experimental results,while the model with the depth-averaged radiation stresses can not reflect the vertical distribution of undertow.  相似文献   

地质事件、序列和事件群   总被引：10，自引：2，他引：10       下载免费PDF全文

陆松年  李怀坤等 《地质论评》2001,47(5):521-526

在前寒武纪变质基底和造山带中，由于多期热－构造事件的影响，以及透入性片理和构造岩的发育，造成变质深成侵入体，构造岩和表壳岩鉴别的困难，。即使表壳岩系统也因强烈的变形而不能够完全运用叠置地层学的方法进行地层划分和对比，因而事件地质学的思路和方法的应用颇为广泛。地质事件是地史演化过程中，不同于正常地质历史发展的突发性，或灾变性，或具有特殊意义的地质记录，在正确识别地质事件的性质和特征的基础上，需建立地质事件的序列，事件序列的建立包括两个步骤，首先要在野外翔实的工作基础上建立地质事件的相对序列，然后在此基础上运用多元同位素测年方法标定主要或特征地质事件的时代，建立地质事件的年代格架。地质事件群或组合则是成因上有联系，空间上相匹配，时间上有先后的一组地质事件，它比单独的一个事件更深刻地反映地质历史演化的过程和特点，正确归并和界定地质事件群在研究区域地质演化特征或进行大区域间的地质对比时具有十分重要意义。  相似文献
