Stability evaluation of rock mass is an indispensable work in the geotechnical investigation stage. How to obtain the strength parameters of rock and soil quickly is one of the main objectives in the engineering practice. A tilt device is designed to measure the basic friction angle of rock mass discontinuity. The structure of the device is simple; it is easy to made and convenient to operate. It could guarantee the steady connection between the measuring point and rock. It is easy to assemble and very suitable for rock discontinuity basic friction angle measurement on site. The results could meet the all kinds of test requirements of reliability and stability.
