砂类土列尔米涅确认,法国建筑及公共工程科学中心利用缩小尺寸的桩的模型不断加荷把,其压入砂砾层中,这种试验方法所得到的资料不能借助于通常应用的评价深埋基础承载能力的公式圆满地加以解释。根据他的这个结论,为了应用这些公式就必须在评价桩的尖端及侧面受力条件时,对土的内摩擦角给予另外的意义。实验表明,第一个角显著偏大,而第二个角则小于所‘研究土层的内摩擦角φ。
The sand-type Tuermini confirmed that the French Architecture and Public Engineering Science Center has used the model of a reduced-size pile to continuously load it into the gravel layer. The data obtained from this test method cannot be evaluated by the usual application. The formula for deep-buried foundation carrying capacity is successfully explained. According to his conclusion, in order to apply these formulas, it is necessary to give an additional meaning to the internal friction angle of the soil when evaluating the force conditions of the tip and the side of the pile. Experiments show that the first angle is significantly larger, while the second angle is smaller than the internal friction angle φ of the studied soil layer.
