expect for especial circumstance, the belled diameter of belled pile and the diameter of equal-diameter pile should not be big excessively.
扩底桩的扩底直径、直桩的直径除特殊情况外,不宜过大;
the way to value the bearing capacity and settlement calculation given herein are fit for the design of large diameter belled pile in china.
文中提出的承载力取值和沉降计算是一套适合于我国大直径扩底桩的设计方法。
the bearing capacity per volume of tapered pile and belled pile are comparatively better.
楔形桩和扩底桩的单位体积承载力相对较好;
the vertical bearing capacity of belled pile is greater than the pure friction pile and shaft as their diameters are equal.
直径相同时,扩底桩的竖向承载力远大于纯摩擦桩和直身墩。
