校准的有限元（FE）模拟越来越多地提供了一个可靠的环境，模拟地震引起的地面变形。可以在统一的框架内评估对地基和上层建筑的影响，并探讨相关的补救技术。通过一个简单的3维（3D）系列的模拟证明了这种FE框架的当前能力。研究了地面荷载作用下地基的液化和沉降。通过土壤压实和/或增加所施加表面荷载下方和周围的渗透性来探索液化危害缓解。数值模拟的潜力和局限性进行了讨论，沿着未来的研究需求和挑战，更可靠的实际应用。
Calibrated Finite Element (FE) simulations are increasingly providing a reliable environment for modelling liquefaction-induced ground deformation. Effects on foundations and super-structures may be assessed and associated remediation techniques may be explored, within a unified framework. Current capabilities of such a FE framework are demonstrated via a simple 3-dimensional (3D) series of simulations. Ground liquefaction and settlement under the action of a surface load is investigated. Liquefaction hazard mitigation is explored by soil compaction and/or increase of permeability below and around the applied surface load. The potential and limitations of numerical simulation are discussed, along with future research needs and challenges towards more reliable practical application.
