Experimental study on vertical bearing capacity of churning driven cast-in-place pile in Xian area
-
摘要: 旋挖钻孔灌注桩是西安地区近年来广泛采用的一种灌注桩形式。通过对西安地区不同场地20余根旋挖钻孔灌注桩静载试验及桩身应力测试结果的分析，论述了黄土地基中旋挖钻孔灌注桩的荷载传递性状，经过与《建筑桩基技术规范》（JGJ94-94）有关规定的比较，初步探讨了这种桩型单桩竖向极限承载力的特性。Abstract: The churning driven cast in place pile is widely adopted in Xi'an area in recent years By analyaing the results of static test and stress test of over 20 such piles at different sites in Xi'an area, the character of load transferring in loess foundation is discussed.Comparing with the regulations of Technical Code for Building Pile Foundation(JGJ94-94),the character of the vertical ultimate bearing capacity of single pile is discussed.
