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。

As the basement to integrate multi-scale spatiotemporal data, the object evolution model can retain the characteristic of the data with different temporal-scale or different spatial-scale, and reflect the temporal changes especially the heteromorphic changes, and the causalities within the evolving process.
本文通过对时空对象变化过程的分析,指出对象进化的结果不仅是特征的变化,还包括机制的变化,其直接动力是对象行为,其根本原因是其内在机制,时空事件起着对象间信息通道的作用,据此提出对象进化模型,该模型可作为多尺度时空数据集成的结构性基础,在反映时空现象的演变过程,特别是异构演变过程,以及在这个过程中产生的因果关系的同时,还可以保留时空数据的不同时间尺度和空间尺度特点,从而达到增加时空数据库的信息量的目的。

At the same time, the biomass of species-rich community was more sensitive to the change of environmental conditions, while communities with fewer species had a little change in biomass.2 There were a total of 87 vascular plant belonging to 27 families and 68 genus in the six communities. Most species had a narrow distribution and a lower local abundance, while few species had a wider range and higher local abundance, and this distribution trends varied in different communities. The endemics were positive correlation to y diversity.
