介绍了微波具有的特性以及微波加热原理,包括偶极极化、离子导电和界面极化三种机制。综述了微波加热技术在岩土工程领域的相关应用,例如快速测定土的含水量、处理固体废弃物、破碎岩石等,概述了该技术在融解冻土、淤泥土脱水、公路再生沥青修复技术方面的成果,并且提出微波加热技术可应用于减少有机土有机物含量、加热快速固结软土,以及微波加热研究的具体方向,期望能推动微波加热技术在岩土工程领域的推广。

Application of microwave heating in geotechnical engineering

This paper presents properties of microwaves and the principle of microwave heating, including three mechanisms, i.e. dipolar polarization, ionic conduction, and interfacial polarization. Then, it gives a review on applications of this technology in geotechnical engineering, such as rapid measurement of water content in soil, disposal of construction wastes, and rock breaking. This article also outlines the application results of this method in melting frozen soil, drying the sludge and rapid repairing of asphalt pavement. It also proposes ideas on consolidation of soil and pyrolyzing organic soil using microwave heating, as well as further studies on microwave heating, which would be helpful to advance propagation of this technology in geotechnical engineering.
