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.

确定了粗粒土与结构接触面厚度约为5～6倍的平均粒径，首次揭示了接触面的细观结构异向性以及由此所引起的宏观剪切异向性，发现了在单调和往返剪切荷载作用下土颗粒破碎和剪切压密两种物态变化机制共同支配着接触面力学性质的变化，通过细观分析证实了接触面的变形可分解为一般同时发生的土与结构交界面上的滑移变形以及结构面位移约束范围之内土体本身的剪切变形两部分，观测到接触面受剪时表现出明显的相对法向位移，并可分解为可逆性和不可逆性两个分量；(4)建立了第一个能够统一地描述单调与往返剪切特性、剪应变与体应变耦合特性、细观结构和宏观剪切异向性以及土颗粒破碎等物态变化特性的土与结构接触面弹塑性损伤本构数学模型，并采用多种法向边界条件复杂加载路径的试验成果验证了新模型的合理性和有效性；(5)提出了新模型的二、三维有限元格式并结合实际边值问题进行了应用计算分析，比较了不同接触面本构模型对计算结果的影响，证实了新模型及其有限元格式不仅能够合理地描述土与结构接触面的主要力学特性，还能够较好地反映土体与结构物在接触面处的滑移、脱开等不连续现象。

Through a systematic review about the development of late years on municipal sludge's disposal by mix-combustion with coal, the environmental allowableness, the thermal performance and the process feasibility of the technology was deeply discussed, the technical characteristics and the present problems was analyzed also. It is proved that, there is evidently technical rationality and good prospect about the technology, and there is also need to perfect and develop the technology in combination with municipal sludge's pre-treating and mix-combustion.

The thinkers of the Lunyu School fully expressed their persistence of individualism and their reconsideration in literary modernity Yet the persistence and escape existed side by side, this mode of behavior and thinking indicated that the self-subject of the modern scholars was illusive and was hard to carry on when the modern scholars were covered by the powerful tradition and deeply controlled by modernity's consciousness of time Chapter Two Reconsidering on the character of modernity with leisure ampleness, resisting the human alienation caused by modern materialism and mechanism with humor, reaffirming the space of self-expression, which formed the humor, the leisure, the modern, and the aesthetic spirit implication of Lunyu School But the modern scholar's powerful inclining to the tradition made Lunyu School's aestheticism draw close to live in seclusion And its aesthetic modernity is also discounted for that reason Chapter Three It is the emotion and the leisure manner owning by the middle aged people that help to bring about Lunyu School's essay's adjusting in main key and moving massively in theme Lunyu School changed the way for "gaining the experience of life"in the twenties'prose It went from highly enthusiastic writings to reserved life-concerning and recite with appreciation in everyday life

第一章 三十年代左翼文学以其"新"、"进步"和"时代性"确立了自己的合理性地位，而时代思潮的转换、文艺与政治的日益密切使五四自由知识分子所坚持的个人主义成了"落伍""颓废"的表征。论语派自由思想者充分表达了对个人主义的执着、对文学现代性的反思，但坚持与逃逸并存的行为与思维模式表明现代士子在忧生伤世的强大传统笼罩下和一往无前的现代性时间意识的深刻控制下，个人主体的难以为继和虚幻性。第二章以闲适的余裕对奔竞躁进、汲汲功利、一往无前的现代性特征进行反思，以幽默对抗现代物质主义机械主义对人灵智的异化，重申自我表现的空间，构成论语派幽默闲适的现代性审美精神内涵。但现代文人对于传统的强大趋同力，则使论语派审美主义向隐逸文化靠拢，其审美现代性由此大打折扣。第三章中年情感与闲适气度直接促成论语派散文基调上的调整及主题的大幅横移，在趣味、游戏、幽默、闲适中改变了二十年代散文"问世"的径路，从意兴湍飞的激扬文字走向了沉潜适世的生命关怀与日常人生的吟味与咀嚼。
