“…According to elastoplasticity theory and dimensional analysis, these similarity requirements can be deduced from force-equilibrium equations, geometry equations, Hooke's law and boundary conditions [10]. Geo-mechanical model test belongs to nonlinear destruction testing, therefore the following four similarity requirements for destruction test should be met:…”

“…Under the deep buried conditions, rock deformation may not belong to elasticity range, the interaction mechanisms of physical nonlinear and geometric nonlinear will make the evolution of rock system extremely complicated [1][2][3]. Similarity theory has been proved to be very useful to solve the problem [4][5]. As a significant method of science research, physical model test is the first introduced model which similar to the prototype in laboratory based on the similarity principles, by observing mechanical parameters and distribution of model with instrument, then deduce possible mechanics phenomenon and pressure distribution of the prototype with results of model, finally solve practical problems of rock engineering.…”

Abstract. Nonlinear progressive failure study of surrounding rock is important for the stability analysis of underground engineering projects. Taking a deep-buried tunnel in Chongqing as an example, a three dimensional(3-D) physical model was established based on similarity theory. To satisfy similarity requirement of physical-mechanical properties, such as elastic modulus, compressive strength and Poisson ratio, physical model materials were developed. Using full inner-spy photograph technology, the deformation and failure process of rock were studied under the situation of independent and combined action of anchor, shotcrete and reinforcing mesh. Based on experimental results, the interaction mechanism between rock and support structure under high stress was investigated.

“…It can scale down the dimensions of prototype project based on the similitude principles to study the engineering and geological issues. It is available to simulate the complex geological structures factually and provide more visualized test results [5][6][7][8][9]. Geomechanical modeling started in the 1960s, when high dam projects were rapidly developing across the world.…”
