Abstract: | It is a systems engineering to successfully simulate a part of a bifurcated tunnel using 3D geomechanical model tests. It involves how to determine the areas and scale for which the model tests simulate, how to choose the similar material which simulates rock mass correctly in geomechanics model tests, how to design and manufacture the steel structure for the models and the manufacture ,excavation and surveying of the models. This paper indicates all the aspects of the systems engineering based on the internal and external model tests including our model tests. Our model tests show that it can’t be a waste of time. The new type similar material may be suitable for all kinds of models. The steel structure for the models satisfies the necessary rigidity of model tests. The models are easily manufactured and excavated. The results of the surveying satisfy the demands of our tests. |
