摘　　要：本文通过对嵌岩基桩进而小型钢管嵌岩桩的受力分析,得出小型钢管的桩身承载力和竖向限承载力的计算方法,从而运用于石灰岩地区复杂地质条件下人工挖孔灌注桩的补强加固是经济、方便、有效的方法。Base on the mechanical analysis of Small steel pipe piles of rock-socketed,this paper describes the computational methodof ultimate bearing capacityand vertical bearing capacityof Small steel pipe rock-socketed piles,which can be applied forthe strengthening and repairing application of excavating pileinlimestone area under the complicated geological conditions,and this is aneconomic、 convenientand effective method.
