摘　　要：水泥搅拌桩的面周比是桩的横截面面积与其周长之比。它是水泥搅拌桩承载力的重要参数之一。通过理论推导和案例分析,笔者建立了水泥搅拌桩单桩承载力和面周比之间的关系。破解了单轴水泥搅拌桩复合地基承载力比双轴高的原因。在软土中以"细而密"的布桩形式可以有效地提高复合地基承载力。Ratio of area perimeter of cement mixing pile is the ratio of pile cross-sectional area to its perimeter. It is one of the important parameters of cement mixing pile bearing capacity. Through theoretical derivations and case analyses, author established a relation between cement mixed pile of pile capacity and area perimeter ratio. Cracked the reason of the uniaxial cement mixing pile composite foundation bearing capacity higher than biaxial. In soft soil by ＆quot;thin and dense＆quot; cloth pile form can effectively improve the bearing capacity of composite foundation.
