21、录数据见附表。资料整理如下：（1）、绘制p-s曲线（ps曲线的必要修正：图解法或最小二乘修正法）根据载荷试验原始沉降观测记录，将（p, s）点绘在厘米坐标纸上。由于ps曲线的初 始直线段延长线不通过原点（0,0），则需对ps曲线进行修正。此处采用图解法进行修正，其中50=0.06 mm,即将曲线整体向上平移 0.06mm。如附图一所示。、绘制s-lgt曲线在单对数坐标纸上绘制每级荷载下的slgt曲线，注意标明坐标名称和单位。同时需要 标明每根曲线的荷载等级，荷载单位用kPa。如附图二所示。、地基承载力特征值fak由于ps关系呈缓变曲线，不宜采用拐点法和极限荷载法确定地基承载力特征值，故采 取相对沉降法。其中，b=0.4m，s/b取0.01，即5 =0.01 0.4=0.004m = 4 mm所对应的荷载作为地基承载力特征值，但其值不大于最大加载量的一半。由ps曲线知，当5=4 mm时，p=100kPa
