During the construction of a deep tunnel, the stresses in surrounding rocks will be redistributed due to the pushing of the tunnel wall while the stresses in wall rocks reach to a disturbed state. Therefore, it is quite important to determine the disturbed zone stress for the design and construction of the deep tunnel. After discussing the features of various techniques used in the measurement of disturbed zone stresses, the borehole measurement technique was used to determine the magnitude and the change with time of the disturbed field stresses in the granite of the deep tunnel. The technique for estimating the detected stable instant of disturbed zone stresses was then proposed by the use of the hyperbolic fitting method. The distribution features of the measured stable disturbed zone stresses in the horizontal and vertical directions were thereafter analyzed. The results show that compared with other methods, the borehole measurement technique is more quick, convenient and feasible, and especially suitable to measure disturbed field stresses in deep tunnels.
