针对对超长桩荷载传递机理研究非常缺乏 ,通过对 3根大直径超长钻孔灌注桩的静荷载试验研究 ,揭示了天津地区大直径超长灌注桩的承载力特性及桩的荷载传递特征 ,并分析了影响其极限承载力的因素。
In view of the lack of research on the load transfer mechanism of super-long piles, the static load test of three large-diameter extra-long cast-in-place bored piles is carried out to reveal the bearing capacity characteristics and load transfer characteristics of the large- , And analyzed the factors affecting the ultimate bearing capacity.
