数值模型通常用于预测液化和侧向扩展的发生和传播。然而，仍然只有少数高质量的数据集来验证这些模型。通过液化实验和分析项目（LEAP）发起了物理和数值建模者之间的国际合作，以建立验证数值模型的标准方法。LEAP的主要目标之一是为数值建模者提供高质量的实验数据，这些数据可用于一系列预测练习。在此框架内，2015年1月在伦斯勒理工学院（RPI）进行了倾斜存款的小规模离心试验，并为土壤液化数值工具的评估提供了全面的数据集。2015年9月重复了相同的实验，以评估RPI物理建模方法的稳健性和可重复性。本文有两个目的：（1）通过实验研究倾斜沉积物的响应和液化潜力;（2）建立用于数值模拟的实验数据的可重复性。
Numerical models are commonly used in practice to predict the occurrence and propagation of liquefaction and lateral spreading. Nevertheless, there are still only a few good-quality data sets to validate these models. An international collaboration between physical and numerical modelers has been initiated through the Liquefaction Experiments and Analysis Projects (LEAP) to establish a standard method for validation of numerical models. One of the main goals of LEAP is to provide numerical modelers with high-quality experimental data that can be used in a series of prediction exercises. In this framework, a small-scale centrifuge test of a sloping deposit was conducted at Rensselaer Polytechnic Institute (RPI) in January 2015 and provided comprehensive data sets for evaluation of soil liquefaction numerical tools. The same experiment was repeated in September 2015 to assess the robustness and repeatability of the physical modeling methods at RPI. This paper serves a double objective: (1) to study the response and liquefaction potential of sloped deposits experimentally and (2) to establish the repeatability of experimental data to be used in numerical simulations.
