刚性挡墙土压力试验装置的研制与应用

Development and Application of Experimental Device for Earth Pressure of Rigid Retaining Wall

为了培养学生的自主创新能力和科研意识,使学生对"土压力"概念有更加深刻的理解,对不同试验条件下土压力沿墙高的分布规律及其影响因素有一个更清晰的感性认识,本文研制了一种刚性挡墙土压力试验装置.该装置由敞口钢结构模型箱、动力推进系统、数据采集与处理系统等部分组成,功能灵活,能实现多种试验条件下的土压力试验教学,便于学生自主设计系列创新性、研究性、综合性土压力试验项目,同时可供师生开展科学研究.该装置已应用于湖南理工学院土木工程专业土压力试验教学,效果良好.

In order to cultivate students'independent innovation ability and scientific research consciousness,so that students have a deeper understanding of the concept of"earth pressure",and have a clearer perception of the distribution of earth pressure along the wall height and its influencing factors under different experimental conditions,an earth pressure test device for rigid retaining walls is developed.The device consists of an open steel structure model box,a power propulsion system,and a data acquisition and processing system.It has flexible functions and can implement earth pressure test teaching under various test conditions.It is convenient for students to independently design a series of innovative,research,comprehensive earth pressure test project,at the same time for teachers and students to carry out scientific research.This device has been applied to the earth pressure test teaching of the civil engineering specialty of our school,and the effect is good and worthy of promotion.
