The main factors affecting the soil-structure interface behaviors were found experimentally and theoretically, including: 1 the thickness of the interface that is five to six times the average grain size of the soil; 2 the aeolotropy of interface, which is responsible for anisotropic response of the stress-strain response of the interface; 3 two physical states, including crashing and compression of the soil near the structure surface, which govern the stress-strain response of the interface strongly; 4 two shear deformation components due to sliding and constraint of the structure surface relative to the soil respectively, which forms the deformation of the interface; 5 the volumetric strain due to dilatancy, which is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. 4. A unified constitutive model of the interface, based on new elasto-plasticity damage theory, was developed. It was confirmed to be effective for the conditions considering monotonic and cyclic shearing, coupling effect of shear and volumetric strains, evolution of physical state, micro-structure aeolotropy of the soil and the resulting aeolotropy of the interface as well as the three normal boundary conditions stated above. 5. 2D and 3D finite element formulations of the present model were derived and incorporated into the FEM codes. They were applied to the evaluation of practical engineering problems with different typical interfaces between soil and structure. The new model was shown to be reasonable and effective.

The fatigue is analyzed for the SENT specimen of TA6V titanium alloy at different stress ratio and on different stress level by the general finite element analysis software ANSYS. The dangerous fatigue location is predicted by the nodal stress Y-direction of the hemicycle notch for TA6V titanium alloy SENT specimen. Based on the local stress-strain method and the material S-N graph, the nominal stress-strain of the specimen is converted to the local stress-strain of the dangerous location by the elastic and plastic finite element analysis, thus the fatigue life is estimated by Miner fatigue damage accumulation theory and compared with the fatigue test of small crack growth.

The theory of Confucianism founded by Lu Gu and Jia Yi was originated from the theory of Xun Zi, However, not the same as the thougt of Lu Gu, in the theory of Jia Yi, which reflected the aristocracy-oriented feature of the upper class, the ideology of aristocratism was aroused. Han Ying initiated the self-awakening man's original mind or nature and reestablished the theory of born good. His theory was regarded as an anabranch of Confucianism in the early stage of Han Dynasty, and a reecho of historical movement of the aristocratic theory of Confucianism advocated by Confucius and Mencius. During the periods of Emperor. Jing of Han and Emperor Wu of Han, an aristocratic upper class had come into being. Therefore, in the face of the society that experienced populace-oriented baptism, Dong Zhong-shu kept down the aristocratic components existed in Jia Yi's theory, absorbed populace-oriented consciousness, which formed the foundation for theoretical system, and transferred instrument-centered Confucianism to the one with sanctification. Thus, Confucianism acquired its theoretical remolding and historical transforming.

汉初的陆、贾儒学的思想理路是由荀学发展而来，但不同于陆贾之说，在贾谊思想里，作为当时上层社会走向贵族化这一时代特征的反映，贵族化思想成分开始被唤起；陆、贾之后的韩婴则倡导心性修养，重建性善论，他的学说是孔孟儒学贵族化历史乐章之回响，为汉初儒学的支流；景武之际，汉初上层社会已经完成了贵族化转变，为此，董仲舒保留了贾谊学说中的贵族化思想成分，然更为重要的是，面对一个经过平民化洗礼的社会，董仲舒吸纳平民思想意识以建构理论体系，将陆贾、贾谊承自荀子的工具性特征显著之儒学转变成具神学特征的儒学，使儒学获得一次理论上的大改铸，实现了儒学的历史转型。

Typical accident-causing" theories includes Heinrich" s Domino" s theory, its development by Bird, Adams and other people, progress of which is that it is deficiencies of management system that are the root cause in accident causation sequence. This is author" s idea resource and main method to produce the water traffic accident-causing theory . in addition, uncontrolled transferring of energy theory, applies widely in safety management scheme for water traffic; human error accident model can be used to analyze causes of collision accident and to take preventive measures; perturbation theory and multilinear event sequencing method is a very useful investigation method to water traffic accidents. All of these theories have contributed to the development of water traffic accident-causing theory. As to orbit intersecting theory, the paper thinks it extension of Domino s theory, although it exists independently.
