挡土墙土压力实验演示装置研制

为了培养学生的实践能力和自主创新能力,使学生对挡土墙的位移影响土压力的分布等问题有感性的认识,加深对基本理论知识的理解,提高学习效率,针对土力学挡土墙中的教学内容,研制了挡土墙土压力实验演示装置。该装置由开口模型箱、挡土板及位移控制装置、测压装置等部分组成,可以用于演示挡土墙的位移对土压力的分布影响。该装置在学生课堂教学中取得良好效果。

An Equipment for Demonstration the Earth Pressure on Retaining Wall

In order to develop students＇ practical ability and independent innovation capacity, a demonstration equipment for showing the earth pressure on the retaining wall is developed. It may help students get a sensible understanding on the influence of the retaining wall displacement on the earth pressure distribution. Meanwhile, it is helpful for students to have a better understanding of fundamental theories and to improve study efficiency. The equipment consists of open model box, retaining panel with displacement control device, pressure-measuring device, etc. It can be used to show the effect on the earth pressure distribution by different retaining wall displacement. Its application in class teaching shows well effect.
