In order to study tracked vehicle adopting different steering mechanism, we use steering power ratio to evaluate its performance. The influencing factors of steering power ratio have been theoretically studied. And we designed the experimental prototype to test. We find that steering power ratio is related to vehicle parameters, resistance coefficient, turning radius, skid ratio, slip ratio and steering coefficient not only, but also it is related to soil parameters (including soil cohesion, internal friction angle of soil and shear modulus of soil). On the condition that vehicle parameters and resistance coefficient are determined, the soil shear tests were carried out, which acquired that the average moisture content of soil is 16.85%，soil cohesion is 14.071 Kpa, internal friction angle of soil is 17.93°, and shear modulus of soil is 0.00027 m. Through being researched, steering power ratio is related to turning radius, skid ratio and slip ratio, which has the important significance on the study of steering power ratio.
