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。

Now, two dozen such societies have sprung up in China, mainly along the coast whose development has brought prosperity (you need money to be a birdwatcher: for binoculars, spotting scope and camera equipment). This growing band is trying to halt the destruction that development has brought, teaching youngsters about the joy of birds and holding local governments and businesses to account when they trash wild places.
现在,这样的团体有二十多个,大都兴起于繁荣的沿海城市(作为一个观鸟者,必须有钱去添置双筒望远镜、射弹观测镜和照相机)这支增长的队伍正努力制止开发造成的破坏,他们教育孩子们,有鸟类在是很愉快的,并坚持让政府和商人统计他们破坏的野地。

The photosynthesis is determined by photosynthesis meterThe results showed that the net photosynthesis rate of Carex lasiocarpa(47.41 μ mol/m/s)is faster than those of other plants in Carex lasiocarpa wetland, Based on the overall sunlight radiation and the efficient photosynthesis radiation, energy utilization rate in radicula was the highest(1.3945% and 3.1879%)While those in spike was the lowest(0.0020% and 0.0046%).
毛果苔草湿地的物理过程观测设在中国科学院三江平原沼泽湿地生态实验站内,用美国CID公司出品的光合仪对典型湿地中几种优势植物的光合能力进行测定;在80℃干燥的植物样品,粉碎后,分别称量约1g左右,用美国公司Parr型氧弹式热量计测定;研究发现毛果苔草湿地建群种中毛果苔草的净光合速率最大,为47.41μmol/m/s。

runaway star:速逃星
据国外媒体报道,日前,哈勃望远镜观测到一颗超大质量速逃星(runaway star)以40万公里每小时的速度从邻近的"恒星托儿所"逃逸,它的惊人逃逸速度很可能是由于超大质量同伴的"弹球游戏"或者超新星爆炸驱逐形成的.
