Comparison on Pile Driving Effect between Driven Cast-in-place Tubular Pile and General Synchronous Pile
-
摘要: 应用圆孔扩张理论,分析了筒桩施工挤土效应,并通过比较,得出筒桩施工挤土效应远远小于普通沉管灌注桩或预制实心桩;筒桩可内外承担摩阻力,承载力高,挤土效应小,是一种比较理想和值得推广的桩型。Abstract: The pile driving effects of driven cast*.in*.place tubular piles are analytically analyzed by making use of cylindrical cavity expansion theory,and by comparison with general piles,its superiorities in respect of disturbing soils are displayed. Because both its inner and external surface can bear friction,and it is hollow,so its bearing capacity is higher and pile driving effect is smaller than any kind else,and is worth being popularized.
