摘要：Reinforced concrete core dams can be an alternative solution to conventional dam designs either for permanent impounded reservoirs or flood protection and flood-retaining dams. Dams of this type have been constructed in Austria for various reasons and have shown good behavior during operation. For a better understanding of the load-deformation behavior of this type of dams during construction and impounding, numerical simulations were carried out. The interaction between the thin reinforced concrete core and the dam fill material as well as the influence of fill material properties and other main parameters, such as the roughness of the concrete surface and bedding conditions of the concrete core,on the deformation behavior of dams were examined. The results show that high compressive stress is mainly induced by arching effects in the dam body during construction. During the reservoir impounding, the compressive stresses in the core are reduced significantly while the bending moment in the core footing increases. The results also show that the maximum bending moments occur at the core footing and can be significantly reduced by design improvements. The findings in this study can provide general design recommendations for small dams with a central concrete core as a sealing blanket.

摘要：The melting and solidification process of sodium nitrate, which is used as energy storage material, is studied in a vertical arranged energy storage device with two different bimetal finned tube designs （with and without additional lateral fins） for enhancing the heat transfer. The finned tube design consists of a plain steel tube while the material for the longitudinal （axial） fins is aluminum. The investigation analyses the influence of the lateral fins on the charging and discharging process. Three-dimensional transient numerical simulations are performed using the ANSYS Fluent 14.5 software. The results show that, every obstruction given by lateral fins reduces the melting and solidification velocity in direction to the outer shell.

摘要：根据与维也纳工业大学化学工程研究所共同确定的实验方案,在实验室开发并设计了一套自由下落装置,研究粉体下落过程中粉尘的排放特性。通过实验主要测定下落高度、空气湿度和质量流量对粉尘排放的影响。实验结果表明,下落高度和空气湿度对粉尘排放均有影响,且空气湿度对粗粒子的排放影响较大,对细粒子影响较小;随着质量流量的增加,粉尘产生率逐渐减小,但质量流量的增加也会增加粉尘浓度,加重了对工人的危害。建立了影响因素与粉尘产生率之间的数学模型,经检验,二者之间存在显著相关,实测值与理论计算值基本一致,可以应用已建立的数学模型定量评价粉尘产生量。

摘要：基于滑坡多级监测概念的欧盟基金项目OASYS是2006年完成的。来自6个国家的12个研究院都试图把滑坡和灾害管理领域中的这些多学科知识融合到一起。本研究的主要目的是，在滑坡灾害密度高的区域，开发一种成本经济的预防滑坡灾害的多级监测与评估系统的概念。本文报道了创新的方法和一些重点的研究，主要是三个任务：◆遥感资料的GIS集成地质评价，大量滑坡所处的高风险区；◆以传感网络设计为基础，利用模糊技术进行监测数据的几何分析；◆以报警系统信息为基础，利用有限差分方法进行滑坡岩土力学的建模。这几个主要任务分别针对的是所取得的成果。在随后的调查中必须实现综合的方案。

摘要：为了研究物料下落过程中随机性粉尘的产生特性,在实验室开发并设计了一套自由下落装置。通过实验主要测定空气湿度和质量流量对粉尘产生率的影响。结果表明,空气湿度对粉尘排放有影响,且对粗细粒子的影响程度不同;当空气湿度达到一定数值时,粉尘产生率已很小,此后再增加空气湿度,粉尘产生率基本不变。随着质量流量的增加,粉尘产生率逐渐减小,但粉尘浓度会增加,对工作场所工人的身体健康及环境带来严重危害。根据实验数据建立了空气湿度和质量流量与粉尘产生率之间的数学模型,经验证,相关性很好,实测值与理论计算值基本一致,可以定量评价不同质量流量下不同空气湿度的粉尘产生率。
