For the first time, a screw pile and pile driver system for preventing flood and rushing to deal with an emergency was manufactured. The screw piles of the system is different from screw drills used to sap, and it doesn't push soils out. Analyses, including the screw pile's structural strength analysis and the screw blade's welding analysis, were done by ANSYS, which showed that the screw pile's structural strength is enough and that the distort of the screw blade is small. Testing on the screw pile and pile driver system showed that the system performed stably and could meet the need of preventing flood and rushing to deal with an emergency. A mechanics model of interaction of a screw pile and soil was built, and expressions of torque of screw pile's cylindrical part on the condition of screw pile's crew part being driven into soil fully were gained, then the relation of the torque with screw pitch and out diameter of cylinder, which shows the torque decreases with the screw pitch increasing, and that the torque increases with the out diameter of cylinder increasing, which was according with the experiments of the screw pile's being driven into soils, and thus a screw pile with the best structure was chosen. Experiments of bionic surface showed that, on the condition of certain pressure on the surface, the protruding bionic surface can not reduce adhesion and resistance and that the corrugated bionic surface can reduce adhesion and resistance. An orthogonal experiment of the corrugated bionic surface was done with the factors including the width of protrusion, the space between two protrusions, the trolley's velocity and the vertical surface pressure and with the surface frictional coefficient as the experimental target, and some inclusions were drawn that the best combination of the factors was acquired and that the width of protrusion affected the surface frictional coefficient remarkably.

研制了防汛抢险螺旋桩机系统,提高了沉桩作业效率;利用ANSYS对桩体进行整体结构强度分析以及螺旋叶片的焊接分析,表明桩体结构强度足够,焊接过程中,螺旋叶片的变形小;对整个螺旋桩机系统进行试验,表明该系统性能可靠,工作稳定,作业效率高,能够满足防汛抢险沉桩作业基本需要;建立了螺旋桩桩土作用力学模型,得出螺旋桩沉桩过程中螺旋桩螺旋部分完全进入土体时螺旋桩圆柱部分所受扭矩以及扭矩与防汛抢险螺旋桩的螺旋导程和圆柱外径的关系曲线,表明螺旋桩螺旋部分完全进入土体时螺旋桩圆柱部分所受扭矩随着螺旋导程的增大而减小,随着圆柱外径的增大而增大,这与螺旋桩沉桩试验结论相符合,据此优选出最佳结构的螺旋桩;仿生曲面试验表明,尺寸较小的球冠突起型仿生曲面在一定压力作用下未能起到减降阻的作用,而尺寸较大的波纹型仿生曲面相对平板具有一定的减降阻作用;以波纹型仿生曲面突起宽度、波纹型仿生曲面两突起之间间距、台车的牵引速度以及叶片表面垂直载荷为因素,以曲面摩擦系数试验指标进行正交试验,寻求出在一定试验条件下最佳因素水平组合;波纹型仿生曲面突起宽度在本试验条件下对曲面摩擦系数影响显著,而其它几个因素对曲面摩擦系数影响均不显著;通过波纹型仿生曲面突起宽度和台车牵引速度的单因素试验,表明曲面摩擦系数随着仿生曲面突起宽度的增大而减小,而随着台车牵引速度的变化基本保持不变,和正交试验结果保持一致。
