在论述软弱地基特征及基坑支护结构现状的基础上,分析了采用土钉墙支护结构支护深度6.0—7.0 m软弱基坑的可行性。在超软弱地基中,用土钉墙来支护深度为6.0 m的基坑,并获得成功,开辟了用土钉墙支护软弱基坑的先例。由于地区的特殊性,应对土钉墙实施过程中可能出现的问题进行预测和预防。详细地介绍了土钉墙设计施工的经验和教训,并提出了适用于特殊地区软土基坑的土钉墙基坑支护型式。由于土钉墙基坑支护结构的经济合理性,可以在我国的基坑支护中推广应用。 相似文献

The models, methods and their application experiences of a practical GIS (geographic information system)-based computer decision-making support system of urban power distribution network planning with seven subsystems, termed CNP, are described. In each subsystem there is at least one or one set of practical mathematical methobs. Some new models and mathematical methods have been introduced. In the development of CNP the idea of cognitive system engineering has been insisted on, which claims that human and computer intelligence should be combined together to solve the complex engineering problems cooperatively. Practical applications have shown that not only the optimal plan can be automatically reached with many complicated factors considered, but also the computation, analysis and graphic drawing burden can be released considerably. 相似文献

ABSTRACTIn recent years, there has been increasing interest within the engineering education research community to prepare engineering students to address wicked problems (WPs) such as climate change, resource scarcity and violent conflict. Previous research suggests that engineering students are able to address WPs if they are given adequate support, but there is a lack of research on what kinds of support are needed. This paper aims to reduce this gap by reporting on students’ performance in, and approaches to, addressing WPs when different scaffolding strategies were used in different parts of a rubric-based intervention. The intervention aimed to provide undergraduate engineering students with an understanding of the nature of WPs and with a structured way of addressing them. For each part of the intervention, we discuss affordances for learning provided by the different scaffolding strategies. The results suggest that strong cognitive scaffolding can support students’ understanding of the nature of WPs and students’ performance in written responses to WPs, but possibly also limits deep engagement with WPs and transfer of learning to other contexts. 相似文献

This paper focuses on the preliminary design of a multifaceted computer-based mathematics resource for undergraduate and pre-entry engineering students. Online maths resources, while attractive in their flexibility of delivery, have seen variable interest from students and teachers alike. Through student surveys and wide consultations, guidelines have been developed for effectively collating and integrating learning, support, application and diagnostic tools to produce an Engineer's Mathematics Gateway. Specific recommendations include: the development of a shared database of engineering discipline-specific problems and examples; the identification of, and resource development for, troublesome mathematics topics which encompass ideas of threshold concepts and mastery components; the use of motivational and promotional material to raise student interest in learning mathematics in an engineering context; the use of general and lecture-specific concept maps and matrices to identify the needs and relevance of mathematics to engineering topics; and further exploration of the facilitation of peer-based learning through online resources. 相似文献
