Abstract :
In order to do the deformation characteristic tests on marble of which the geostress level is above 60MPa, a set of rigid pressure plates test equipment for center hole method and an automatic servo and acquisition system is developed. It consists of power transmission system, servo load system and measurement system. This paper mainly introduces the system structure, working principle and functions. It is shown by the application in a deep buried tunnel in a hydropower project that the equipment system has high loads, high precision, stable, reliable, and easy to operate. It can solve rock mass deformation test question under high stress and achieve good application effect.
