摘　　要：通过对旋转触探用双螺旋探头的受力分析,建立了螺旋探头的贯入阻力和扭矩与贯入速度和转速,以及岩土的力学性能参数间的数学模型。结合数学模型和试验数据对旋转触探技术的影响因素进行了分析,为设计探头结构和进一步理解该技术的力学机理提供了理论依据。This paper studied the relationship between penetration resistance or torque and penetration speed, the geotechnical parameters of the mechanical properties, through establishing the mathematical model with the me- chanical analysis of the double helix probe. Combined with mathematical models and experimental data, the factors on the impact of the penetration technology are analyzed. The conclusion may afford theoretic basis for designing the probe structure and understanding the mechanic mechanism of the penetration technique.
