Lunne Aims & Scope Geomechanics is concerned with the application of the principle of mechanics to earth-materials (namely geo-material). Geoengineering covers a wide range of engineering disciplines related to geo-materials, such as foundation engineering, slope engineering, tunnelling, rock engineering, engineering geology and geo-environmental engineering. Geomechanics and Geoengineering is a major publication channel for research in the areas of soil and rock mechanics, geotechnical and geological engineering, engineering geology, geo-environmental engineering and all geo-material related engineering and science disciplines. The Journal provides an international forum for the exchange of innovative ideas, Submission Instructions especially between researchers in Asia and the rest of the world. Potential authors should submit The Journal welcomes papers concerned with any aspect of geomechanics their full paper through the and geoengineering, including material behaviour, analysis procedures, ScholarOne Manuscripts system. design and construction. Papers published may take one of the following forms: practioners’ detailed records of construction and performance (case For detailed directions, please visit studies), academic research studies, state-of-the-art reviews by invited Instructions for Authors. authors, symposia in print, technical notes and discussion. While paper submissions from all parts of the world are equally welcome, the Journal is committed to publish high quality papers from China and other Asian countries.
