通常情况下桩身摩阻的分析需要借助桩身应力观测,但对于摩擦型的长桩在非极限荷载的情况下,其荷载的作用增量基本转化为桩身的摩阻增量,且荷载的作用深度是渐进的,根据这一特征可以通过Q-S曲线间接分析桩身摩阻的变化情况,相对于复杂的桩身应力观测而言,该方法不失为一种较经济的分析手段。

The results show that Q-s curves calculated and measured are close to each other.
可以发现计算与实测的Q-s曲线非常接近;墩底端阻力的发挥严重滞后于墩侧摩阻力,墩顶荷载主要由端阻力承担,属摩擦端承型;扩大头侧面与土体接触处产生裂缝,裂缝首先在侧面下部产生,随荷载增加逐渐向上发展直至贯通,最大裂缝宽度达4。
2.
The study then starts with the calibration of single pile by analyzing the possible reasons to induce the difference between the measured and calculated Q-S curves.
先对一根试验桩进行验证计算,分析计算Q-S曲线与实测Q-S曲线存在差别的原因,然后对38根不同嵌岩深度和不同桩径的泥岩桩进行计算,模拟出泥岩桩的Q-S曲线和Q-z曲线,并对其统计分析,进一步论述了泥岩桩的荷载传递过程及其承载性状。

性质:又称塔菲尔(Tafel)线外推法。一种测定腐蚀速率的方法。做法是将金属样品制成电极浸入腐蚀介质中,测量稳态的伏安(E~I)数据,作log|I|~E图,将阴、阳极极化曲线的直线部分延长,所得交点对应的即为logIcor,由腐蚀电流Icor除以事先精确测量的样品面积S0,即得腐蚀速率。此法快速省时,适用于金属均匀腐蚀的测量。
