5、1、加载方法本条格式不限，但应讲透，包括加载方式和加载设备，举例如下：2、试验通过天然地基提供支座反力，用液压千斤顶在反力梁上逐级加压，用位移传感器测读每级荷载的上拔量。加载、补压、控载、判稳及测读记录 沉降量的全部工作均由RSM-JCIII型静力载荷测试仪自动控制完成。采用慢速维持荷载法测试单桩竖向抗拔极限承载力标准值。试验设计最大加载量见表1。加载分九级进行，采用逐级等量加载，分级荷载为最大加载量 的1/10,其中第一级取分级荷载的2倍.每级荷载施加后按第5、15、30、45、60min测读桩顶上拔量，以后每隔30min读一次。当一小时内的桩顶上拔量不超过0.1mm并连续出现两次（从分级荷

6、载施加后第30min开始，按1.5h连续三次每30min的沉降观测 值计算），即可加下一级荷载。卸载分5级进行，每级卸载量取加载时分级荷载的 2倍。卸载时，每级 荷载维持1h,按第15、30、60 min测读桩顶上拔量后，即可卸下一级荷载。 卸载至零后，应测读桩顶残余上拔量，维持时间为3h,测读时间为第15、30min,以后每隔30min测读一次。3.终止试验条件当出现下列情况之一时终止加载：在某级荷载作用下，桩顶上拔量大于前一级上拔荷载作用下的上拔量5倍。按桩顶上拔量控制，当累计桩顶上拔量超过100mm寸。按钢筋抗拉强度控制，桩顶上拔荷载达到钢筋强度标准值的0.9倍。当加载至设计要求的最大上

7、拔荷载值但不满足以上3条规定时，可继续加载2级，加载2级后仍不满足以上3条规定时，可终止加载。.单桩竖向抗拔极限承载力的确定按建筑基桩检测技术规范4.4条、5.4条的规定对单桩竖向抗拔静 载试验的数据进行整理分析，确定单桩竖向抗拔极限承载力及承载力特征 值，或根据设计要求的最大上拔量确定。根据试验数据绘制的荷载与上拔位移变化关系曲线 （U 6曲线）、上拔位 移量与时间对数关系曲线（Slgt曲线）确定单桩竖向抗拔极限承载力 Ua, 当Ua后最大试验荷载时，判定该检测桩满足设计要求.检测设备现场检测设备一览表表4型号编R量程准确度检定日期检定后效 期千斤顶百分表/ 位移传感器8压力表/ 压力传感器
