摘　　要：以某化工类地基处理项目中预制钢筋混凝土方桩的单桩竖向抗压极限承载力试验为例,分析了单桩竖向抗压极限承载力试验检测预制钢筋混凝土方桩在工程中遇到的问题,指出单桩竖向抗压静载试验适宜安排在地下水位回归正常水位、土体重新固结基本完成之后进行,能够准确判断桩基抗压极限承载力。Taking a single pile vertical compressive ultimate bearing capacity test of a precast reinforced concrete square pile in a chemical foundation treatment project as an example,this paper analyzes the vertical compressive ultimate bearing capacity test of a single pile to detect the precast reinforced concrete square pile encountered in the project. It is pointed out that the vertical compressive static load test of a single pile is suitable to be arranged after the groundwater level returns to normal and the soil consolidation is basically completed. It can accurately determine the ultimate bearing capacity.
