本文总结了参加LEAP-2017预测演习的11个数值模拟(预测)团队提交的单元测试模拟(校准模拟)。大量的单调和循环三轴(Vasko,通过单调和循环剪切试验对渥太华砂的行为进行的调查。硕士论文,乔治华盛顿大学,2015年; Vasko等人,LEAP-GWU-2015实验室测试。DesignSafe-CI,数据集,2018; El Ghoraiby等人,LEAP 2017:渥太华F65砂的土壤表征和元素测试。乔治华盛顿大学,华盛顿,2017年; El Ghoraiby等人,LEAP-2017 GWU实验室测试。DesignSafe-CI,数据集,2018; El Ghoraiby等人,渥太华F65砂的物理力学性能。在B。Kutter等人(编辑),液化和侧向扩展的模型试验和数值模拟:LEAP-UCD-2017。纽约:Springer,2019)和直接简单剪切试验(Bastidas,渥太华F-65砂表征。博士论文,加州大学戴维斯分校,2016年)可用于渥太华F-65砂。本单元试验模拟练习的重点是评估参与团队在模拟渥太华F-65砂三种不同孔隙比的不排水应力控制循环三轴试验结果时使用的本构模型的性能(El Ghoraiby等人,LEAP 2017:渥太华F65砂的土壤表征和元素测试。乔治华盛顿大学,华盛顿,2017年; El Ghoraiby等人,LEAP-2017 GWU实验室测试。DesignSafe-CI,数据集,2018; El Ghoraiby等人,渥太华F65砂的物理力学性能。在B。Kutter等人(编辑),液化和侧向扩展的模型试验和数值模拟:LEAP-UCD-2017。纽约:Springer,2019)。模拟的应力路径,应力-应变响应,和液化强度曲线表明,大多数的模型在这个练习中使用的是能够提供一个合理的良好匹配的液化强度曲线的最高孔隙比(0.585),但模拟和实验之间的差异变得更大的较低的孔隙比(0.542和0.515)。
This paper presents a summary of the element test simulations (calibration simulations) submitted by 11 numerical simulation (prediction) teams that participated in the LEAP-2017 prediction exercise.

The focus of this element test simulation exercise is to assess the performance of the constitutive models used by participating team in simulating the results of undrained stress-controlled cyclic triaxial tests on Ottawa F-65 sand for three different void ratios (El Ghoraiby et al., LEAP 2017: Soil characterization and element tests for Ottawa F65 sand. The George Washington University, Washington, DC, 2017; El Ghoraiby et al., LEAP-2017 GWU Laboratory Tests.

(Eds.),Model tests and numerical simulations of liquefaction and lateral spreading: LEAP-UCD-2017. New York: Springer, 2019). The simulated stress paths, stress-strain responses, and liquefaction strength curves show that majority of the models used in this exercise are able to provide a reasonably good match to liquefaction strength curves for the highest void ratio (0.585) but the differences between the simulations and experiments become larger for the lower void ratios (0.542 and 0.515).
