Abstract: 
For geohazards and geotechnics, numerous problems involve large deformation, such as the installation of foundations, landslides, debris flow, collapse of underground structures, and the formation of sinkholes (Barandiarán Villegas, 2018). Benefitting from the sustained development of computing power, numerical simulations have become useful analytical methods in geomechanics and related fields. This special issue contains original research articles on the application of numerical methods to large deformation analysis of geohazards and geotechnics. Focal points of the issue include innovative uses of: (1) mesh-based methods, (2) mesh-free particle methods, (3) mesh-based particle methods, (4) discontinuous numerical methods, and finally (5) practical applications of the above techniques, e.g. case studies and benchmarking exercises.

岩土工程及灾害的大变形模拟

概要:岩土工程破坏以及灾害往往伴随着大变形问题.近年来,随着计算机技术的快速发展,大变形数值模拟方法在岩土工程领域有了广泛应用,例如利用物质点法(MPM)或者光滑粒子流体动力学法(SPH)模拟边坡垮塌、软土地基中的基础沉降或失稳,利用耦合拉格朗日-欧拉法(CEL)分析隧道破坏对临近地下结构物的影响等.为此,本专辑收集了在该研究领域具有代表性的研究成果,介绍了岩土工程大变形模拟技术的进展和未来发展潜力,希望能帮助读者快速了解其应用现状,并为岩土工程的数字化发展提供科学依据和技术支撑.
