摘　　要：为了寻求防汛抢险螺旋桩体表面仿生曲面结构,通过台车牵引试验,进行了球冠突起型仿生曲面与平板对比试验以及波纹型仿生曲面与平板对比试验,从而确定两种仿生曲面的减粘降阻效果。试验结果表明在本试验条件下,球冠突起型仿生曲面未能起到减粘降阻作用,而波纹型仿生曲面具有一定的减粘降阻效果,为螺旋桩体表面仿生处理提供依据。Experiments of comparison of the protruding bionic surfaces and the common plate surfaces were made, at the same time, experimental of comparison of the corrugated bionic surfaces and the plate surfaces were made. The experiments＇ results showed that, on the certain condition, the protruding bionic surfaces can not reduce adhesion and resistance and that the corrugated bionic surfaces can reduce adhesion and resistance, which provided the basis of the structure of screw piles＇ bionic surfaces.
