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。

Wastewater containing titanium pigment was treated by microfiltration membrane, Nanometer titanium can be purified and concentrated by use of microfiltration. Operational conditions were optimized and the model was built. Finally, the amount of wash water was reduced. Based on the above research, the whole set equipment was designed, which can meet the needs in a titanium industry with a capability of 500 ton per year. Backflush and automatic control were used in the equipment, which has been steadily run two years, has been widely adopted in titanium industry. The technology has been widely adopted in titanium industry.In the recent years, whole set equipment of ceramic membrane was increasingly used in the recovery of desired production from fermentation broth in China. A new membrane process integrated with pretreatment of flocculation or coagulation was exploited to recover Inosine. ZrO2 ceramic membrane was used in the work, and the average permeation flux could reach 150L/m2.h under pH value of 3, transmembrane pressure 0.1MPa, CFV 3m/s, and temperature higher than 70C. The recovery ratio of inosine is higher than traditional recovery method, although inosine degraded under acidic and high temperature condition.
