| 摘 要： | 为了探讨厦门砂土的动力特性,对厦门金秋豪园场地的中粗砂和细粉砂做了一系列振动三轴试验,并对同一场地的含泥中砂做了4个共振柱试验。根据试验结果,确定了中粗砂与细粉砂的液化曲线和动本构关系,提出了相应的动孔压模型,得到了含泥中砂在小应变条件下动剪切模量和阻尼比的变化规律。

| Abstract: | In order to study the dynamic characteristics of sands in Xiamen city, a series of dynamic triaxial tests were conducted for the medium-coarse sand and the thin-fine sand at Jinqiuhaoyuan site, and 4 resonant column tests were performed for the medium sand with slurry inclusion. According to the research results, the liquefaction curve and the constitutive relationship for the medium-coarse sand and the thin-fine sand were established; and a model of pore water pressure for the two kinds of sands was proposed. The change regularities of dynamic shear modulus and damping ratio for the medium sand with slurry inclusion were obtained. |
