利用楼群连廊模拟地下工程进行工程测量实践教学的探索

为了锻炼测绘专业学生实际动手能力,提高实践教学质量,促进双师型教师队伍的成长,设计了利用长度400余米的楼群连廊模拟地下工程进行工程测量实践教学的方案,开发了模拟地面控制测量,模拟两井几何定向,模拟竖井导入标高,模拟地下平面控制测量,模拟地下高程控制测量,模拟竖直方向的贯通测量,模拟通过竖井、平峒的贯通测量,模拟隧道变形观测,模拟隧道施工放样,模拟绘制隧道平面图、断面图等十个实训项目。上、下课时的学生人流,模拟了隧道施工中的车流环境;园环形的廊道,增加了测绘工作难度,丰富了学生应对困难现场的经验。系统有针对性地模拟了地下工程测量的过程,有利于实践教学的规范化。

Exploration on training of underground engineering survey in porch linking buildings

To increase the students' ability,we establish a system simulated underground project.In this paper,we discuss how to carry on the survey practice in the porch which links the 6 teaching buildings at Henan Engineering Institute campus.The project simulates the ground control survey,one-shaft orientation,two-shaft orientation,elevation transmission through shaft,the underground horizontal control survey,the underground elevation control survey,the go through survey in a vertical direction,the go through survey in shaft and in horizontal tunnel,the deformation observation in tunnels,the setting out work in tunnels,the horizontal plan mapping of tunnels and the profile survey etc.The whole system simulates the underground survey process well,the stream of students in the porch before and after class simulates the stream of vehicles in the tunnel;the ring-like porch though increases the training difficulty but also enriches the student's experience facing to difficult scene.The underground survey practice is carried at the campus,which saves a lot of money and found a new way of establishing a characteristic teaching base in the school campus for practice.
