摘要
结合实验分析土在螺旋钻具上的动态，以求得螺旋钻具在掘削土的过程中所消耗的扭矩，为设计提供依据。
in this paper. through combining the theory analyses with experimental studies dynamicform of the soil on the screw of the earth auger was analysed and loss of torque of the earth auger inthe process of digging up the soil was obtained. It supllies reliable informetion for designing the earthauger.
