Abstract: This paper presents a design sketch for the physical model test box for the underground space and engineering. The test box consists of steel plate and hot rolled steel corners connected with horizontal whalers and bolts. The four corners of the test box are formed by the steel corners and plates with bolts. This type of connection forms the skeleton of the box and it can also minimize the slip of the soil inside the box. The paper also provides the design sketch of the model test box.
