Geotechnical Field Investigation Equipment for the Instruction of Civil and Environmental Engineering Undergraduates

确定地下剖面的特征对岩土工程来说是一个独特的挑战。因此，有抱负的岩土工程师在进入专业实践之前掌握现场勘探策略和采样技术的知识是很重要的。在大多数岩土工程课程中，学生通过教科书和录像带学习这些主题。这种做法不受行业专业人士的欢迎，因为学生无法真正感受到典型的现场调查所涉及的工作和思想。岩土工程课程的主要目标是通过实践方法将现场测试程序整合到本科课程中。教师认为，学生必须对现代岩土勘探实践有一个完整的了解，如果他们要欣赏岩土工程设计所需的判断。该项目提供了一个车载移动B-53 Explorer钻机和配件。钻机和配件补充和升级了岩土工程项目的现场测试能力（已经使用了锥贯仪和平板膨胀仪现场测试系统），并允许教师将现场测试程序整合到本科岩土工程课程的许多不同方面。工程学院、土木及环境工程系及岩土工程界均认可该计划的价值和需要。所有人都意识到，一个理解和欣赏网站探索策略的学生，在毕业时更能有效地解决现实世界的问题。作为这个项目的一部分，学生的准备，或课程改进的有效性，可以由一个实践岩土工程师团队来评估。＊

Defining the characteristics of a subsurface profile is a challenge that is unique to geotechnical engineering. It is important, therefore, that aspiring geotechnical engineers have a knowledge of site exploration strategies and sampling techniques before entering professional practice. In most geotechnical programs, students are taught these topics using textbooks and videotapes. This practice is frowned upon by industry professionals since the students are unable to get a true feel for the work and thought involved in a typical site investigation. A primary goal of the Geotechnical Engineering program is to integrate field testing procedures into the undergraduate curriculum using a hands-on approach. The faculty believe that students must have a complete understanding of modern geotechnical exploration practices if they are to appreciate the judgment required in geotechnical engineering design. This project provides a truck-mounted Mobile B-53 Explorer drill rig and accessories. The drill rig and accessories complement and upgrade the Geotechnical Engineering program's field testing capability (cone penetrometer and flat-plate dilatometer field testing systems have been utilized) and allow the faculty to integrate field testing procedures in many different aspects of the undergraduate geotechnical curriculum. The value and need of the proposed project have been recognized by the College of Engineering, the Civil and Environmental Engineering Department, and the geotechnical engineering community. All realize that a student with an understanding and appreciation of site exploration strategies is better prepared to effectively solve real-world problems upon graduation. As part of this project, student preparedness, or the effectiveness of the proposed curricular improvements, can be evaluated by a team of practicing geotechnical engineers. *
