国外某高孔隙比地基土工程特性研究

国外某电厂分布有高孔隙比、高压缩性粘性土,这类粘土虽然承载力较高,但在承受建筑物荷载时会产生较大压缩变形,从而影响上部结构稳定性。本文通过对该工程地基土的岩土工程勘测研究分析,得出该高孔隙比粘土的岩土工程特性,虽其承载性能较好,但不能作为沉降敏感建筑物的天然浅基持力层。本文研究结论可以为该地区进行其它工程建设提供参考。

分散性粘土鉴别方法及工程防治措施研究综述

分散性粘土是一种抗冲蚀能力很低的土,其在我国及国外均有分布.分散性粘土在雨水或低含盐量水流作用下易发生崩解并被带走,其在水中分散的实质足土粒间的联结在水的作用下破坏的过程,也是土粒间斥力超过吸引力,使得相互排斥作用占优势的结果.因此有许多用分散性粘土修筑的土坝、渠道及堤防工程在降雨或渗流作用下会产生管涌、冲蚀裂缝、孔洞或在坡面形成沟槽等破坏.自20世纪60年代以来,研究者对分散性粘土进行了大量的研究和治理工作,取得了有价值的成果,并在工程实践中发挥了重要的指导作用.本文从分散性粘土的分散机理、分散性粘土的鉴别方法以及分散性粘土的工程防治措施等三个方面对近年来所取得的研究成果进行分析和总结;展望分散性粘土研究的发展趋势,提出该领域应重点研究的课题.

Engineering Disaster Relief

The large-scale systems engineering (LSSE) frameworks deal with complexities of large-scale systems and providing disaster relief can be considered as a large-scale system. Applying the large-scale system engineering approach, this article provides a framework in which such disaster relief could be carried out. Using the 2004 Asian Tsunami as an example, specific instances from the assistance rendered by Singapore and by other entities are included that illustrate aspects of the deployment of a disaster relief framework.     

Situation Problems in Electrical Engineering

During the past few years, I have developed a couple dozen problems in Electrical Engineering which are somewhat unusual. The problems are written around a situation similar to case studies as employed in Business Schools. I try with some introductory comments to project the student into a "real life" situation and then lead him through a series of step-at-a-time solutions. One of the purposes of the situation problems is to heighten the student's interest and thereby increase his motivation. Additionally, the student learns to follow through a lengthy line of reasoning and related engineering design. Since the problems frequently require the full use of broad prior knowledge, the student learns to integrate together a number of subjects. In this respect, the problems help to augment his laboratory experience. The situation problems typically require a considerable amount of time both by the student in solving and by the instructor in grading. Occasionally, the problems are done in groups or as class exercises. The problem answers follow sequentially and initial errors are propagated. This is justified as being a "real life" experience and therefore valuable to the student in teaching him to work accurately The over-all student reaction has, I feel, been quite favorable. In discussing the solutions, the instructor has an opportunity to interpolate numerous comments, as appropriate, concerning analysis, approximations, and engineering design philosophy. The following situation problem on "Transistorized Low-Frequency Class C Amplifier" was recently prepared.     

Engineering Reality in Single-Answer Problems

The purpose of this work has been to investigate one method by which some of the outside reality of the world of engineering can be presented in single-answer problems. The technique involves a tool readily available to all engineering educators: the current technical literature. Single-answer problems are particularly important in the earlier phases of engineering education, when they serve to develop the student's capacity to use fundamental intellectual abilities such as recall and manipulation. Textbook problems are typical. They are generally considered to have little direct relation to the real world of engineering. However, if some of this outside reality can be presented in such problems, the student will perceive them as relevant and will be motivated to higher levels of achievement.     

Software Engineering Education

Recent trends have led to the expanded use of digital computers in large complex system applications. The major burden of meeting the requirements for these systems has fallen on the flexibility of software. This has placed many demands on all areas associated with digital systems development. A significant impact has been on the development of software personnel required to develop and manage these complex systems. The purpose of this paper is to present a three level program for software education of executives, managers, and engineers which is being offered at the Air Force Institute of Technology (AFIT). The needs and approaches in satisfying software engineering education requirements are presented. Educational objectives for executives, managers, and engineers serve as the foundation of the curricula, courses, and topics presented.     

Engineering Approach to Engineering Education

Various suggestions for modification of the electrical engineering curricula are briefly reviewed; importance of the laboratory is discussed; and guidelines for a new curriculum, based on a reasonably equal division between theory and laboratory, are presented.     

RCA Minorities in Engineering Program

A nationwide effort, guided by NACME (National Action Council for Minorities in Engineering), is underway to increase the number of minorities in the engineering profession. The RCA-MEP (Minorities in Engineering Program) seeks to identify talented minority high school students and provide them with an in-depth orientation on the engineering profession. The program is presently in its eighth year, and so far, over 1600 students have participated at 14 plant locations nationwide. The program is described in this paper, as are the results of a survey of over 500 students in 1980. Indications are that a substantial number of students have decided to choose an engineering career path and are presently enrolled at many of the nationwide engineering schools.     

Cooperation between Engineering Societies and Engineering Schools in Continuing Education Programs

Engineering societies such as the IEEE have long held a close concern for, and have had a formal impact on engineering education. Only recently, however, have societies taken a programming interest in continuing professional education. The continuing education interests of engineers generally are represented in the Continuing Engineering Studies Division of the American Society for Engineering Education. This organization is continuously seeking ways to offer better programs to more engineers, at locations and times convenient to the working engineer, and at reasonable cost. The inter-relationship of the engineering societies, educational associations and universities and colleges in continuing engineering education is discussed. An example of an integrally cooperative program, the "Professional Certificate Program," now under development at UCLA, is described in detail.     

Engineering to help

A growing number of U.S. universities offer classes, initiatives, programs, or degrees in engineering and sustainable development, community service, service learning, and/or humanitarian engineering. (To name just a few, in the United States [19], [20], [32], [33], [44], [53], [54].) Similar programs are also burgeoning in Australia, Canada, Europe, and elite universities in Latin America. Although these programs are conducted under a number of auspices and with varying objectives, they share one thing in common: an expressed desire to "help" communities "in need." Such programs generally hold as objectives the performance of some needed service and learning via reflection by those performing the service. To be inclusive, we refer to this diversity of programs under the umbrella term "engineering to help" (ETH).     

Continuing Engineering Education and the IEEE

Considering continuing education in its broadest sense, the IEEE has provided a wide variety of learning experiences since its founding in 1884. Indeed, the type and number of offerings has become so diffuse as to cause a "masking" effect to develop conceming its educational role over the years. While continuing to provide a plethora of educational material, the IEEE in recent years has attempted to focus on specific tutorial material directed at its individual member audience as well as its geographic units, utilizing the most effective media at its disposal. The programs currently underway are described and some thoughts on the directions the Institute might go in the future are discussed.
