某桥墩桩基偏位分析与纠偏实施效果   总被引：3，自引：0，他引：3  

裴碧峰 《福建工程学院学报》2005,3(4):385-388

根据桥墩桩基施工现场的具体情况，通过理论计算，分析了两基桩产生偏位的主要原因。采用卸载止推、反向堆载、挖坑卸荷、强力牵拉等综合纠偏方法对产生偏位的两基桩实施纠偏，经过一个多月的缓慢纠偏使两桩基基本恢复原位，纠偏后经桩身低应变动测（反射波法）检测其桩身完整满足设计要求。  相似文献   

论党的三代领导集体对民主集中制建设的探索     

李朝阳  励维志 《天津师范大学学报(社会科学版)》2002,(1):6-10,16

中国共产党自成立以来,对民主集中制建设进行了坚持不懈的探索。坚持民主集中制原则中国化的方向,是党的三代领导集体在不同的历史条件下不断发展这一原则的宝贵经验,也是我们按照“三个代表”的要求,加强民主集中制建设必须遵循的根本原则。  相似文献   

被动荷载作用下邻近桩基的研究概况与进展     

陈福全  潘钦峰 《福建工程学院学报》2004,2(1):23-32

岩土工程师们不仅经常要评估已有桩基在侧向土体运动条件下的响应特性，而且经常要设计抗滑桩以加固不稳定不安全的边坡或阻止有可能坍滑的山体。在很多工程实例中，工程桩常常在土层侧向位移作用下工作，导致桩体弯矩和挠度过大，使相邻桩基产生水平偏位，从而引起上部码头、桥梁及工业厂房等结构功能失效或引发事故。文章系统地总结了在这些条件下现有的各种被动桩土压力理论、试验成果和计算方法，分析了在各种影响因素作用下被动桩的变形机理与性状。  相似文献

Experiential learning in doctoral training programmes: fostering personal epistemology through collaboration     

Cho Kwong Charlie Lam  Cuong Huu Hoang  Ricky Wai Kiu Lau  Basil Cahusac de Caux  Yang Chen  Qiao Qian Tan 《Studies in Continuing Education》2019,41(1):111-128

There has been increasing recognition for the need to reform doctoral training practices to foster students’ personal epistemology. This study describes the design and evaluation of a learning experience designed to help students understand the scholarly publication process. Firstly, this study discusses the design of the learning experience, describing the collaborative process of writing an interdisciplinary publication using both online and face-to-face learning. Secondly, this study evaluates the effectiveness of the learning experience by examining students’ reflections. We show that participation in the learning experience helped students to develop their academic writing proficiency, collaboration and teamwork, intercultural competence, and ability to engage in reflective practice. Importantly, we show that each student also created more individualised knowledge, gaining insight into how they and others think. This study, therefore, demonstrates that personal epistemology can be fostered through collaboration in a doctoral writing group context.  相似文献

Students’ educational use of Facebook groups     

Christian Dalsgaard 《Educational Media International》2016,53(4):261-273

The aim of the article is to explore educational use of student-managed Facebook groups in upper secondary education (in Denmark). Much research on educational potentials of Facebook has studied groups managed by teachers. However, there is a lack of in-depth research on Facebook groups managed by students and without participation from teachers. As this study shows, students’ use of student-managed groups differs from their use of teacher-managed tools such as learning management systems (LMSs). The article presents an empirical study based partly on a content analysis of 3139 posts and 15,018 replies within five Facebook groups, and partly on a questionnaire answered by 1463 students and 148 teachers. The results of the study show that whereas LMSs were seen by students primarily as institutional systems of the teacher, Facebook groups have an educational potential to be used by students for peer-to-peer learning.  相似文献   

高职扩招背景下三类重点群体的人才培养模式探析——以财经专业群为例     

夏冰 《职业技术教育》2020,(5):23-26

教育部《高职扩招专项工作实施方案》的发布,标志着高职院校扩招100万进入实施阶段。此次扩招的对象主要是退役军人、下岗工人以及农民工三个重点群体。新型招生群体的出现要求各高职院校亟需制定学制和授课形式灵活、可操作性强、符合地方经济和产业发展水平的人才培养模式。财经类专业群与理工类、农学类、医学类等专业群相比有其独特优势,更加适合上述群体,在人才培养中可采用灵活的学制、授课形式及置换课程方式。  相似文献   

Simple groups with orders 2^a3^b5^cp^d, 2^a3^b7^cp^d and 2^a3^b5^c7^d     

JIANGYouyi TANMingshu LIUXuefei 《重庆大学学报(英文版)》2004,3(1):105-107

This work deals with the power exponent r1 and r2 respectively of the maximal and second-maximal prime factors ofthe order of simple K4-group, and the classification for simple {5,7}′-K4-group G (i.e. ｜G｜ can not be divided by 5 nor by 7 or ｜π(G)｜ = 4 ), simple 5′ -K4-group G (i.e. ｜G｜ can not divided by 5 and ｜π(G)｜ =4) and simple 7′-Ea-group G (i.e. ｜G｜ can notdivided by 7 and ｜π(G)｜ =4). It is derived that r1 =1, 2 and 4, and r2 is not greater than 4. All the simple K4-groups with order 2^a3^b5^cp^d, 2^a3^b7^cp^d and 2^a3^b5^c7^d are obtained.  相似文献
