21、錄數(shù)據(jù)見(jiàn)附表。資料整理如下：（1）、繪制p-s曲線（ps曲線的必要修正：圖解法或最小二乘修正法）根據(jù)載荷試驗(yàn)原始沉降觀測(cè)記錄，將（p, s）點(diǎn)繪在厘米坐標(biāo)紙上。由于ps曲線的初 始直線段延長(zhǎng)線不通過(guò)原點(diǎn)（0,0），則需對(duì)ps曲線進(jìn)行修正。此處采用圖解法進(jìn)行修正，其中50=0.06 mm,即將曲線整體向上平移 0.06mm。如附圖一所示。、繪制s-lgt曲線在單對(duì)數(shù)坐標(biāo)紙上繪制每級(jí)荷載下的slgt曲線，注意標(biāo)明坐標(biāo)名稱和單位。同時(shí)需要 標(biāo)明每根曲線的荷載等級(jí)，荷載單位用kPa。如附圖二所示。、地基承載力特征值fak由于ps關(guān)系呈緩變曲線，不宜采用拐點(diǎn)法和極限荷載法確定地基承載力特征值，故采 取相對(duì)沉降法。其中，b=0.4m，s/b取0.01，即5 =0.01 0.4=0.004m = 4 mm所對(duì)應(yīng)的荷載作為地基承載力特征值，但其值不大于最大加載量的一半。由ps曲線知，當(dāng)5=4 mm時(shí)，p=100kPa
