摘　　要：采用弹性无限半空间体内的Mindlin应力解和分层总和法，计算分析了柔性桩的荷载传递规律，较详细地讨论了桩长、固化剂（水泥）掺入量对柔性桩复合地基承载力、变形的影响。计算值与实测值比较吻合。This paper adopts Mindlin formula in elastic medium and layering summation to calculate and analyse 1oad transmiting rule for flexible piles, and studies in detail the influence of the length of the pile and mix-ratio on the bearing capacity and deformation of the flexible pile. The computation results are verified by comparing with those of the field test.
