摘要
从稳定性分析方程出发,通过对步履式桩架在悬挂长螺旋钻机时立柱的受力进行力学模型简化,研究了它的稳定性,并讨论了斜撑在不同支撑位置对整个力柱稳定性的影响,并给出了对具体问题的稳定性校核方法和算例.
The leader of the walking pile frame was analyzed in a simplified mechanical model when it was appended on a long screwing driller. According to the equation of the stability analysis, we studied the stability of the leader, and the effects of different supporting positions on the stability were discussed. The stability checking method and calculated examples of specific problems were also presented.
