In the program of LEAP-Asia-2019, three dynamic centrifuge model tests on a 5-degree sloping ground composed of saturated Ottawa F-65 sand have been conducted at Zhejiang University to validate the generalized scaling law (GSL) by using the technique of "modeling of models". Firstly, the advantages and possible limitations of the generalized scaling law are revisited. Then a new scaling relation (GSR) treating the stiffness instead of the strain as an independent scaling factor is proposed in the frame of the generalized scaling law, and it further considers the effect of modulus reduction over wide strain range. Shear wave velocities of three models measured by bender elements and non-destructive step wave are analyzed to check the validity of Iai's Type II GSL at small strain range, and the response of acceleration, excess pore water pressure and displacement are analyzed to validate Iai's Type II GSL at large strain range. This study shows that Iai's Type II GSL generally applies well for small strain conditions and even the dynamic response of acceleration and pore pressure, but will introduce considerable errors for dissipation time and permanent displacement under large strain conditions. The proposed GSR exhibits better performance for all model tests from small to large strain levels.

在LEAP-Asia-2019计划中，浙江大学已在由饱和渥太华F-65砂组成的5度倾斜地面上进行了三个动态离心机模型测试，以通过使用“模型建模”。首先，重新讨论了广义缩放定律的优点和可能的局限性。然后在广义尺度定律的框架内提出了一种新的尺度关系（GSR），将刚度而不是应变作为一个独立的尺度因子，并进一步考虑了在较宽应变范围内模量减小的影响。分析了由弯曲元件和非破坏性阶梯波测得的三个模型的剪切波速度，以检验Iai II型GSL在小应变范围内的有效性以及加速度的响应，分析了多余的孔隙水压力和位移，以验证大应变范围下Iai的II型GSL。这项研究表明，Iai的II型GSL通常适用于小应变条件，甚至加速度和孔隙压力的动态响应，但会在大应变条件下为耗散时间和永久位移引入相当大的误差。对于从小到大应变水平的所有模型测试，建议的GSR表现出更好的性能。但会在大应变条件下为耗散时间和永久位移引入相当大的误差。对于从小到大应变水平的所有模型测试，建议的GSR都具有更好的性能。但会在大应变条件下为耗散时间和永久位移引入相当大的误差。对于从小到大应变水平的所有模型测试，建议的GSR都具有更好的性能。
