Microstructures and micromechanics of geomaterials
岩土材料(如黏土、砂土、岩石和混凝土等)在颗粒尺度上均具有独特且明显的微观结构(如组构、粒径、颗粒形状、矿物组成、接触模式和内部孔隙等)。这些颗粒尺度的微观结构较难直接观察,但对岩土材料的宏观物理力学行为(如剪切**度、压缩性和渗透性等)有着显著的影响。**年来,各种新型岩土工程材料(如纤维增**土和生物加固土)表现出更加复杂的微观结构。岩土材料微观结构对材料工程性质的影响促使人们采用更加先进的理论、实验和数值方法对其进...

Physical model testing in geotechnical engineering
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...
