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 uncovered tracts and the liver wound surface were managed by some of the methods combined such as high frequency electrocoagulation, titanium clamp, suture, hemostatic gauze oppression, argon-beam coagulation, protein glue adherence, and Endo-GIA switcher. The total operative outcome, operating time, blood loss, postoperative complications and postoperative hospital stay were summarized in order to assess feasibility and safety of the clinical laparoscopic liver resection.Results: 1. Laparoscopic liver resection with clamp dissection method needs only the ordinary laparoscopic equipment. It has a low cost but causes a little more bleeding. 2. Laparoscopic liver resection operated by microwave tissue coagulation method had very little bleeding when dissecting hepatic parenchyma. The operative field is clear and the cost is low. It is a safe, convenient and effective method. 3. Ultrasound dissector is a relatively ideal appliance for laparoscopic liver resection at present because ofless bleeding during operation. But the speed is slow thus prolongs the operation time. Its separating intensity is not strong enough, and it can only be applied to patients without hepatic cirrhosis. 4. Ligsure has clamp dissection and electrocoagulation functions. It can carbonize hepatic tissue including the tracts whose diameters are less than 7mm. It has some advantage in dissecting. However, it has the shortcomings of the clamp dissector during coagulating. 5. Hand-assisted laparoscopic liver resection can make use of the flexibility and feeling of the operators left hand.

The plastic deformation induced due to cyclic rotation of principal stress axes alone can be in the same magnitude as that due to shear with fixed principal stress axes. 2 The volumetric strain due to shearing of cyclic rotation of principal stress axes is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. The former is characterized by its reversibility and is independent of past shear history, the latter by its irreversibility increases with the increase of cycle number yet its increase rate decreases with its accumulation. 3 The obvious non-coaxiality between directions of the principal stresses and principal strain increments is found and its degree depends largely on the change of shear stress component. 4 The intermediate principal stress has considerable effects on the deformation behavior of sands in the condition of cyclic rotation of principal stress axes. The accumulation rate of the irreversible dilatancy component increases with the increase of the intermediate principal stress parameter.

Similarly, if the strong shear, which could suppress all the scattering in the quiescent two phase region, stopped, the follow-up phase separation also displayed characteristics of anisotropism and relaxation, In this dissertation, the transposed"butterfly'and"streakpattern were observed for the first time within the shear-history-influenced phase separation, which is found closely relevant to the anisotropical relaxation behavior of macromolecules. 5. The phase separation kinetics of PS/PVME under oscillatory shear was further studied on the base of that done under simple shear. It is found that, under specific temperature and strain amplitude, the occurrence of phase separation is strongly contingent on oscillatory frequency and only intermediate frequency could effectively induce phase separation; If all considered oscillatory shear could stimulate phase separation, a fixed frequency can maintain specific most probable phase size and higher frequency yields smaller phase, which makes a higher elasticity but weaker stress relaxation; Furthermore, higher frequency can produces stronger compulsory oscillation on the MPPS but won't change the mean of the MPPS. Under given frequency and strain amplitude, the phase separation kinetics dramatically depends on the phase angle of oscillation and the phase separation corresponding to different phase angle follows different dynamical process.
在简单剪切场下相分离动力学研究的基础上进一步对振动剪切场下PS/PVME的相分离动力力学进行了尝试性的研究,发现:在一定温度和振幅条件下,相分离的发生强烈的依赖于振动频率,只有中等频率的振动剪切才能有效地促进相分离的发生;在都能使相分离发生的前提下,一定频率的剪切能够使体系维持一定的最可几相尺寸,较高频率的剪切导致体系形成的相区尺寸较小,因而体系的弹性效应较强而应力松弛效应较弱;同时,更高频率的剪切对最可几相尺寸的强迫振动效应越强,但不会使最可几相尺寸的平均值发生改变;在一定的振幅和频率条件下,相分离的动力学过程会强烈地依赖于相位角,不同相位角对应的相分离遵循不同的动力学过程但机理一样。
