混凝土结构施工中施工缝的留置及处理

在工程建设中对混凝土的浇注过程,常常需要根据施工条件,施工方法,施工人员素质与社会及周边环境设置各种施工缝,并对施工缝采取必要的补强、加强,以及材料准入制度,以达到工程施工的有序性和合理性,有效的防止和控制由于施工缝设置而出现的工程质量问题。     

施工阶段划分模式对悬浇连续梁（刚构）施工预拱度的影响分析

悬臂浇筑的连续梁（刚构）桥施工中须设置施工预拱度,该预拱度的设置有多种影响因素。通过分析与实例计算结果表明,这些影响因素中容易被计算者忽视的施工阶段划分方式恰恰是对施工预拱度的设置具有决定作用的因素。     

后浇带的设置与设计

近年来,在设计和施工方面常采取有效措施,尽量增大结构伸缩缝间距或者是不设置伸缩缝,以减少工程造价及降低施工难度.在适当增大伸缩缝最大间距的各项措施中,常用的做法是设置施工后浇带.本文结合工程实例,就如何设置和设计施工后浇带进行简单的阐述.     

厚大墙体模板支设及对拉螺栓的设置

城市污水处理厂的施工技术一直在发展,在污水处理构筑物施工中,模板的支设是一项关键工序,其效果直接影响到构筑物的外观、混凝土的密实度和构筑物的防水性能。石家庄桥西污水处理厂工程中,结合生物池的结构特点,确定池壁模板施工方案及施工操作要点,通过计算确定模板支设中对拉螺栓的设置,确保模板设置的经济性,可靠性和安全性。为相关工程提供借鉴。

柔性浅基础下变刚度垫层设置的有限元分析

柔性浅基础不具备调整地基变形的能力,针对这一缺点,可在基底应力较大的部位设置强度较大的垫层,而在应力较小的部位设置强度较小的垫层,即通过在基底设置中心刚度大、边缘刚度小的变刚度垫层,以有效调整地基土的应力分布,改善地基土工作性状。采用PLAXIS2D有限元软件,分析比较了柔性浅基础下设置不同工况的变刚度垫层对地基土中应力分布及基础差异沉降的影响．发现在基底中部0．5～0．6倍基宽范围内设置变刚度垫层时,差异沉降控制效果最好。     

宁高城际轨道挂篮施工中移动防护棚的技术应用探析

挂篮施工连续梁一般上跨既有道路比较常见,安全防护可采用固定式防护棚（设置在道路上）和随挂篮一起行走的移动式防护棚。由于既有道路车流量较大,如在道路中央设置固定式防护棚,不仅影响行车安全,而且投入多,办理报批手续复杂;因此挂篮施工连续梁在上跨既有道路时,为确保行车、行人安全,在静高满足要求的前提下通常采用移动式防护棚。本文对宁高城际轨道跨省道悬臂挂篮施工中采用移动式防护棚的技术要求以及在施工中应注意的安全、技术问题进行了总结、分析,以便在类似施工防护中加以推广应用。

Optimization of conditions for supercritical fluid extraction of flavonoids from hops (Humulus lupulus L.)

INTRODUCTION The hop plant (Humulus lupulus L., Cannabi- naceae) is a dioecious twining perennial widely cul- tivated throughout the temperate zones of the world. The inflorescences (hops or hop cones) are used in breweries to give beer its characteristics such as fla- vor and aroma. In this respect, the bitter acids and essential oils have received much attention. Carbon dioxide (CO2) is currently the most accepted solvent for the manufacture of hops extracts by breweries. Its extracts…

Productivity in educational psychology journals from 2003 to 2008

Productivity of individuals and institutions in educational psychology journals has been previously examined in three separate studies (Hsieh et al. [Hsieh, P., Acee, T., Chung, W., Hsieh, Y., Kim, H., Thomas, G. D., et al. (2004). An alternate look at educational psychologist’s productivity from 1991 to 2002. Contemporary Educational Psychology, 29, 333–343]; Smith et al. [Smith, M. C., Locke, S. G., Boisse, S. J., Gallagher, P. A., Krengel, L. E., & Kuczek, J. E., et al. (1998). Productivity of educational psychologists in educational psychology journals, 1991–1996. Contemporary Educational Psychology, 23, 173–181]; [Smith, M. C., Plant, M., Carney, R. N., Arnold, C. S., Jackson, A., Johnson, L. S., et al. (2003). Further productivity of educational psychologists in educational psychology journals, 1997–2001. Contemporary Educational Psychology, 28, 422–430.]) spanning the years 1991–2002. The present study updates this literature by examining the same five journals: Cognition and Instruction, Contemporary Educational Psychology, the Educational Psychologist, Educational Psychology Review, and the Journal of Educational Psychology from 2003 to 2008. Individual productivity was calculated by the number of (a) articles published and (b) points based on a formula that considers author position in relation to the number of authors. The University of Maryland and Richard E. Mayer maintained their positions as the top research institution and author, respectively. There was also growth in collaboration as well as international involvement as measured by number of authors.
