黄河大堤土体三轴抗拉试验研究与应用

Study and Application on Triaxial Tensile Test of Soil From Dike of Yellow River

土体的抗拉特性与土堤裂缝的产生直接相关,因此,正确认识土的抗拉特性和准确测定抗拉强度指标就显得十分重要。在土体强度特性的研究中,过去多侧重于抗压强度和抗剪强度,对抗拉强度的研究较少。针对黄河大堤典型土质开展了三轴抗拉试验研究,得出了许多有益成果,并就具体应用方法进行了探讨。

Tensile property of the soil is relative to existence of dike cracks, therefore, it is important to understand its tensile property and determine the tensile index. Through study on triaxial tensile test of soil from the dike of Yellow River, a lot of beneficial results are achieved. And the applicated method is discussed.
