论公路软基施工质量控制

软基处理在公路施工中较普遍,做好软基处理施工质量控制和施工监控,对把握路堤稳定、沉降等非常必要。根据大量公路软基施工实践,从施工机械、原材料、施工安排、施工过程、施工效率、成品检验、制度约束等方面提出了公路软基处理施工质量的综合控制方法。

某高速公路水泥搅拌桩施工质量控制及检验

高速公路软基处理采用水泥搅拌桩属于隐蔽工程,如施工质量不好,一旦被路堤及构筑物覆盖,便构成隐患且难以检查和补救。某高速公路S01合同段软基处理采用水泥搅拌桩,该施工方法的两个关键节点是:事前优化配合比设计,事中严格按试桩工艺进行施工并加强质量控制,最后采取合适的方法进行桩体质量检测评定。施工实例证明:控制关键节点是取得水泥搅拌桩良好施工质量的重要保证。

公路含泥炭层软基应用粉喷异构桩试验分析

安徽沿江高速公路TY段采用粉喷异构桩施工,实践证明粉喷异构桩在含泥炭层的软基处理中效果显著。同时比较说明,得出水泥搅拌桩在含有泥炭层的软基处理中效果不理想。     

关于路桥路基施工前准备的分析

通过公路调查结果表明,软基路段由于地基沉降引起的桥头跳车现象主要是施工图设计时,地质钻探布孔过少,钻探深度不够,未能及时发现软基存在,或者未能准确探明软基范围和深度以及软土的物理力学性质等等,导致桥头路堤软土地基处遗漏,或采取的处治方法不恰当.本文针对路桥工程的路基施工前的准备工作进行分析和探讨.     

围墩式沙体围堰的施工技术及应用效果

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

The Reader Response Approach to Teaching of English Literature

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context.
