Background
In recent years, with the improvement of economic level and the acceleration of urbanization process, the shield construction technology in China is gradually developed and matured. In the shield tunneling process of the shield tunneling machine, a cutter on a shield cutter head continuously acts with a soil body on a tunneling surface, a large amount of heat can be generated, and the heat can be quickly transmitted to the whole cutter head in a conduction mode. During the normal tunneling process of the shield cutterhead, the heat can be dissipated through a shield system or the surrounding soil body, and cannot cause great influence on the cutterhead. However, as the shield advances, mud cakes are formed on the surface of the cutter head and continuously grow, the hardening speed of the mud cakes is increased by the increase of the temperature, so that the cutting function of the cutter is reduced, eccentric wear is caused, and the torque of the cutter head is increased. Therefore, researching the influence rule of different temperatures on the adhesion of the mud cakes is an effective means for solving the problem of mud cake formation of the cutter head.

In the middle and later period of the 90 s, Jilin university Lushao Fang, Shi Yao Wu et al introduced computer technology into the development of soil adhesion instrument in the article of multifunctional soil laboratory bench, and the automation of the soil adhesion instrument was primarily realized. In 2002, the Wangbushen of Jilin university can realize the measurement of the soil adhesion force under different motion modes such as triangular waves, sine waves and the like by modifying an electronic universal testing machine in the research of the soil adhesion characteristic testing system, and in 2005, the Sulbilk of Jilin university further improves the sampling frequency, the control parameters and the like of the soil adhesion testing system in the research of the sampling frequency and the control parameters of the soil adhesion characteristic testing system. However, the research of these adhesion force measuring devices cannot effectively test the change of the adhesion force under the influence of different temperatures, and does not relate to the heating of the special curved surface by the light temperature rise, and the measurement of the adhesion force value and the rule of the change of the adhesion force along with the temperature under different light time and light temperature by changing the temperature by the light time and the light intensity.
