摘　　要：通过河南省电力公司综合调度楼工程试桩的单桩竖向抗压承载力检测,验证单桩竖向极限承载力满足设计要求;同时分析试验数据,得出了普通灌注桩与后压浆桩桩身轴力、桩身侧阻力和桩端阻力的分布规律,并指出桩身侧阻力为提高后压浆桩竖向抗压承载力的主要影响因素。Through the vertical compressive bearing capacity test of single pile for the scheduling building of Henan Electric Power Company, the design thereof is demonstrated to meet the requirement; at the same time, the test data is analyzed so as to obtain the distribution laws of the axial force of the common-grouting and post-grouting piles and the resistance on the side and top of the piles ; moreover, it was concluded that the side resistance is the main factor considered in improvement of the vertical compressive bearing capacity of post-grouting pile.

关 键 词：普通灌注桩 后压浆桩 承载力 侧阻力
