Single factor experiments were done with the factors including the width of protrusion and the trolley's velocity, which showed that the surface frictional coefficient decreases with the width of protrusion increasing, and doesn't change with the trolley's velocity changing, which was consistent with the results of the orthogonal experiment. A theoretical model of the horizontal projection of a corrugated bionic surface's contact area was built, which showed that the contact area's horizontal projection decreases with width and interval increasing respectively and that the ratio of the contact area's horizontal projection and the vertical load decreases with the vertical load increasing. It indicated that the surface frictional coefficient decreases with the above three factors increasing respectively. Finite element modeling and analysis of interactions of a plate and soils was done using ANSYS, which showed that the plate frictional coefficient is little relative to soil elastic modulus and decreases with vertical surface pressure and that trolley's pull and vertical displacement of bionic surface's control pilot keep constant almost during the plate being pulled. Finite element modeling and analysis of interactions of a corrugated bionic surface and soils was done using ANSYS, which showed that surface frictional coefficient is little relative to soil elastic modulus and decreases with bionic surface's structural parameters and vertical pressure increasing. However, the three factors all didn't affect the surface frictional coefficient remarkably on the condition of 90% dependability. For the first time, bionic surfaces were applied to screw piles, which formed bionic screw piles, and the contrast experiments showed the bionic screw pile had certain resistance-decreasing effects.
建立了波纹型仿生曲面与土壤的接触面积的水平投影的理论模型,表明接触面积的水平投影A随着波纹型仿生曲面突起宽度、两相邻突起间距的增大而减小,接触面积的水平投影与波纹型仿生曲面表面垂直载荷之比随着波纹型仿生曲面表面垂直载荷的增大而减小,进而得出仿生曲面摩擦系数随着波纹型仿生曲面突起宽度、两相邻突起间距以及表面垂直载荷的增大而减小;利用ANSYS软件对平板与土壤的相互作用进行了有限元建模与分析,表明平板摩擦系数与土壤弹性模量关系不大,而随着表面垂直载荷的增大而减小;平板牵引过程中台车牵引力和仿生曲面控制节点垂直方向位移基本保持不变;利用ANSYS软件对波纹型仿生曲面与土壤的相互作用进行了有限元建模与分析,表明波纹型仿生曲面系数在一定范围内基本不受土壤弹性模量的影响,随着波纹型仿生曲面突起宽度、两相邻突起间距以及表面垂直载荷的增大而减小,但在可信度为90%的前提下,三个因素影响都不显著;首次将波纹型仿生曲面应用于与土壤作用方式以挤压为主的螺旋桩,形成仿生螺旋桩,并与普通螺旋桩进行了沉桩对比试验,表明波纹型仿生曲面应用于螺旋桩桩体表面具有明显的降阻作用。
