一、试样砂试验用的试样采用运输省港湾技术研究所提供的万代岛砂。该砂物理性质如下:土粒比重=2.67 1,D_(10)=0.25毫米,均匀系数=1.9e_(max)=1.007;e_(min)=0.590。二、试验方法及条件试验都是对上述砂土的饱和试样以施加周期剪应力的方法进行的。进行试验的单位 1. The test specimens used for the sand test are the Bandai sands provided by the Hong Kong Technical Research Institute of the Ministry of Transport. The physical properties of the sand are as follows: Pellet specific gravity = 2.67 1, D_(10) = 0.25 mm, Uniformity coefficient = 1.9e_(max) = 1.007; e_(min) = 0.590. Second, the test methods and conditions The tests are carried out on the above saturated sand samples by applying periodic shear stress method. Units conducting the test
