摘　　要：在分析传统障碍桩清除施工方法局限性的基础上,提出障碍桩清除设备的6项功能需求,并对拔桩设备机架、动力、套管、导向、切削和监控6大系统进行了模块化设计。通过数值模拟的方法,分析了钢套管受扭压时不开孔、开方形孔、开椭圆形孔3种方案的应力和变形,基于分析结果对钢套管进行了优化设计。Based on the limitation analysis of tradition obstacle piles removing method, 6 functionalrequirements of obstacle piles removing equipment are put forward. 6 system modules, consist of equip-ment frame, motive power, drive pipe, guiding, cuting and monitoring system module, are designed. Bymeans of numerical simulation, 3 models of steel drive pile under twist and pressure condition, includepile with no hole, square hole and ellipse hole, are analyzed. At last, optimization design is carried outbased on the analysis of results.
