摘要
泥岩地基中大直径、中长桩的荷载传递机理的研究比较缺乏。根据西宁地区某工程试桩的竖向抗压静载试验和高应变动力检测结果,通过对桩身轴力传递和土阻力发挥性状的分析,揭示了该地区泥岩地基中大直径、中长钻孔灌注桩的承载特性和荷载传递机理,以及影响其承载特性的因素,得出了一些对泥岩地基中钻孔灌注桩的设计、施工和深入研究具有指导意义的结论。
According to the data of static loading test and dynamic high strain test of pile in Xining city,the bearing properties and loading transmission mechanism of the large-diameter and medium-long borehole cast-in-place piles in muddy rock foundation,as well as the influencing factors on its bearing properties are revealed by analyzing pile axis pressure transmission and soil resistance properties. The study result is instructive for design,construct and deep study of borehole cast-in-place piles in muddy rock foundation.
