Abstract: 
Several characteristics of natural soils complicate the relationship between their mechanical behaviour and geotechnical construction and maintenance in the field. These characteristics include the presence of three phases (solid particle, water, and air), particle constitutions of various minerals (such as quartz, kaolinite, and montmorillonite), and an exceptionally wide range of particle size from μm-scale (clay particles smaller than 2 μm) to 100-mm scale (such as some gravels and pebbles), with complicated inter-particle contact distributions. Field or in-situ testing is the most reliable way to reveal the real conditions for geotechnical engineering (Chen et al., 2021; Xue et al., 2021). However, field testing is sometimes not easy or even not realistic to perform because of resource shortages, time limitations, and difficult operability. To overcome these issues and to reproduce the mechanical or thermo-hydro-mechanical-chemical (THMC) coupled behaviours of geotechnical structures, physical model testing is an efficient and reasonable approach, widely used by academics and engineers around the world (Wang et al., 2018; Guo and He, 2020; Bian et al., 2021; Lei et al., 2021; Tang et al., 2022).

概要:土的三相组成(土颗粒、水和空气)、土颗粒由多种矿物成分构成(比如石英、高岭石和蒙脱石等)以及土颗粒粒径从微米级跨度到100毫米级决定了土的复杂性,从而造成了岩土工程结构设计、建造及维护的复杂性。为了复原现场岩土结构的复杂多场特性,物理模型试验是一种有效、合理且被广泛认可的方法。与现场测试相比,物理模型试验具有高还原度、低价格和高可操作性等优势,同时可充分考虑众多影响因素对实际工况的影响。为此,本专辑收集了在该研究领域具有代表性的研究成果,介绍了多个利用物理模型试验揭示复杂岩土问题机理以及基于试验结果提出设计方法和建议的最新研究进展,涵盖了交通基础设施、盾构掘进、侵蚀、冻土和地震灾害等多个复杂岩土工程问题。希望能加深读者对各个研究领域的理解,以及进一步推动物理模型试验在岩土工程中的应用和发展。
