沉浸式边坡工程虚拟仿真实验项目构建探讨

Discussion on construction of immersive slope engineering virtual simulation experiment project

岩土类专业课程实践性较强,以实际边坡治理工程为基础素材,从学生视角出发,设计11项实验任务,采用游戏软件常用鼠标键操作方法,在野外现实场地仿真系统引导提示下进行交互式自主综合实验学习。通过选择不同位置和角度,观察辨识场地稳定性、边(滑)坡地表及其地下特征要素。根据地表变形破坏特征推断主滑方向,自主设计布置剖面线及勘察钻孔,绘制钻孔柱状图、剖面图及视倾角图。通过对各种工况下边坡稳定性及剩余下滑力进行计算,模拟分析抗滑桩及截水沟布置,加强学生对边坡工程勘察和稳定性分析及设计过程的认知与理解。工程地质等课程引入实验项目后,通过形象逼真的场景和震撼的效果,激发学生的学习兴趣,实现岩土类系列课程之间的教学活动关联,加强理论教学与实践相结合,有效促进学生对知识点的理解,并增强了实践动手能力。

Geotechnical courses are highly practical.Based on the actual slope treatment engineering and from the perspective of students,11 experimental tasks are designed.The mouse key operation method commonly used in game software is adopted to conduct interactive independent comprehensive experimental learning under the guidance and prompts of the field simulation system.By selecting a different position and angle to observe and identify site stability,surface and subsurface characteristics of the slope(landslip),according to the characteristics of surface deformation to infer the main direction of sliding,independently designing section line and the survey borehole,drawing borehole histogram,section,and calculating the apparent dip,calculating slope stability and remaining sliding force under various working conditions,simulating and analyzing the arrangement of anti-slide piles and drainage ditch,to enhance students’cognition and understanding of slope engineering investigation,stability analysis and design process.After the introduction of engineering geology,soil mechanics,slope engineering and other courses in experimental project,the vivid and realistic scenes and shocking effects have attracted and stimulated students’interest in learning.At the same time,the teaching activity correlation and course interconnection of geotechnical series courses have been realized,and the combination of theoretical teaching and practice has been strengthened.
