Abstract：With the technology center of Shanghai Tunnel Engineering Construction Co. Ltd.，development and utilization of underground space，the shield-tunneling method is used wildly as an important construction method. However，due to the regional difference of stratum properties，the working parameters of shield machine will vary in different ways. To better understand the interrelation between the machine working parameters and the variation characteristic of stratum，it is necessary to conduct the model experimental research on shield machine¢s working parameters applicable to stratum property. Therefore，the silty sand stratum in Shanghai area is taken as prototype，then the similitude theory and model test method have been applied successfully to the design of a special test scheme. Subsequently，in different types of ground，various working parameters of shield machine are combined to test. Based on the test results，some useful relationships can be deduced，which will provide good adaptability of shield machine to different strata.
