嵌岩灌注桩竖向承载性状试验研究

TEST STUDY ON THE VERTICAL LOAD BEARING PROPERTIES OF ROCK-INLAID CAST-IN-PLACE PILE

根据某工程3根嵌岩灌注桩单桩竖向静载试验数据,分析嵌岩桩在受荷时的轴力传递、侧阻力发挥和桩端阻力特征,揭示了嵌岩灌注桩的承载特性和荷载传递机理及影响其承载特性的因素,得出一些对嵌岩灌注桩的设计、施工和深入研究具有指导意义的结论。

Based on the data of dead load test of three rockinlaid castinplace piles for a project, analysis is made on the loaded piles in respects of transmission of axial pressure, properties of lateral resistance and character of end resistance, and the load bearing properties of the piles and their influential factors as well as load transmitting mechanism are revealed. The results thus obtained may be instructive to the design, construction and further study of rockinlaid castinplace pile.
