Abstract In geotechnical engineering，the moisture content of shallow embedded soil directly affects mechanical property in the surrounding rocks and crucial important issue of the stability of tunnel. Based on the characteristics of ground penetrating radar(GPR) is sensitive to the water in soil，sampling red clay from tunnel face，adjusting the moisture content of experimental samples from 10% to 30%，and scanning it by variety of frequency of GPR. In consequence，a relationship of moisture content of red clay and the speed of GPR wave is set up. Through continuous monitoring for many times，the moisture content of surrounding rock are obtained by geological radar scanning，and the mechanical parameters as well as its changes related to the moisture content within the detection ranges are predicted. Therefore，moisture content distribution and mechanical parameters of tunnel excavation are revealed as the excavation process of changes occurring in the course of migration，and give a rapid quantitative assessment on the stability of tunnel.

Key words： soil mechanics ground penetrating radar red clay relative dielectric constant moisture content rock stability
