The inclinometer system is one of the important instruments to measure the attitude parameters of shield machines, so that the shield machines can advance along the designed alignments. Once the inclinometer systems on the shield machines manufactured by Mitsubishi Heavy Industries are destroyed, beside high procurement cost and long procurement duration, great losses may be imposed due to longterm construction suspensions when international procurement is adopted. If inclinometer systems made in China are used to replace the destroyed systems, however, the cost can be reduced, normal construction can be guaranteed and the performance of the inclinometer systems can be improved. The key of developing Chinesemade inclinometer systems lies in the substitution of the inclinometers and conversion modules. In the paper, the author presents the substitution and type selection of the inclinometers, the substitution methods of conversion modules, the calibration procedures of the initial parameters, the malfunctions that may occur to the inclinometer systems after the substitutions and their countermeasures. Owing to the adoption of the inclinometer systems made in China, the repairing and maintenance of the shield machines become easier, the performance of the shield machines is improved and the homemade technological level of the shield machines is increased.
