离散元法在贵阳某层状岩质边坡稳定性分析中的应用

以实际工程为背景,介绍了贵阳某层状岩质边坡的特点,分析了边坡的破坏机理及破坏模式,采用二维离散元法对该边坡进行了稳定性分析,指出了在前缘临空情况下,边坡容易发生滑移-拉裂破坏。模拟计算结果与理论分析相符,说明用离散元法分析层状岩质边坡的稳定性是可行的。     

A Context-Aware Medical Instant Message Middleware

Communication or the lack of it has been complained to be a major contributor to medical errors in healthcare.To enhance communication in hospital,diverse communication mechanisms are proposed.However,human directed communication in a complex clinical setting in which many people play diverse roles and need to collaborate in many parallel tasks is always in chaos and inefficient.Context-aware communication which can help target who should be communicated and what information should be provided for different scenarios has the potential to improve the communication in hospital.This paper proposes a flexible,automated and asynchronous context-aware medical instant message(IM)middleware which support dispatch,forward and routing different message to the right person in the right time based on the context information.A prototype of this IM communication middleware was implemented in real clinical setting for evaluation.The preliminary results demonstrate its novel features and clinical feasibility.

The underground sewer drainage design analysis of highway subgrade under evaporation

According to the water balance principle, the expression of the phreatic table is established by considering evaporation and considering evaporation & drainage respectively. The law of phreatic table variation under the combined effects of considering evaporation & drainage is obtained. Based on Newton-Raphson itera-tive method, calculation and analysis programs are done to solve the first order implicit differential equation of the sewer drainage calculation considering phreatic evaporation. The calculation results show: after considering phreatic evaporation, in the need of reducing the same height of phreatic, the sewer spacing is appropriately larger than the case which didn’t consider the affection of phreatic evaporation; the phreatic drop speed in both effects of evaporation and drainage is faster than the case of just considering the drainage effect. Phreatic evaporation has a great influence to the subgrade sewer distance, phreatic evaporation needs to be considered in the subgrade drainage design.

曲线纤维变刚度壁板的亚音速气弹稳定性研究

针对曲线纤维变刚度复合材料层合板在高速列车壁板结构轻量化设计中的广阔应用前景,研究了弹性、黏弹性变刚度复合壁板在亚音速流场中的气动弹性稳定性问题. 首先,基于Mindlin厚板理论和势流流动理论分别描述壁板结构变形和亚音速气动力,根据虚功原理和有限元法建立了曲线纤维变刚度复合材料弹性/黏弹性壁板的气动弹性稳定性分析模型,进而采用复模态理论求解复合材料变刚度壁板发散临界速度;在验证方法正确性和收敛性的基础上,研究了壁板关键参数等对复合变刚度壁板发散失稳特性的影响规律. 研究结果表明:与直线纤维壁板相比,通过调整曲线纤维路径可以实现壁板的发散临界速度50%左右的提升,有效增强壁板气动弹性稳定性.      

基于基波海洋建模的末制导雷达海杂波仿真

传统的海杂波建模方法考虑海面变化较少,导致仿真出的杂波与实际杂波相差较大。海洋表面风场具有随意性,而海情等级与海洋表面风场密切相关。为使海杂波仿真与作战环境相结合,提出了一种应用于基于基波海洋建模的末制导雷达海杂波仿真方法,并通过实验对方法进行了验证。
