本文是陈宗基先生在1962年12月土力学基础工程年会上的发言稿。他阐述了研究我国存在的六个特殊土力学岩体力学问题——水分对黄土的破坏作用、软土和淤泥、土流变学、土动力学、岩体力学、土物理化学和矿物学——的重要性和研究途径。会上大家感到很有启发,我们特请陈先生整理成文,以供读者参考。 This article is the speech of Mr. Chen Zongji at the annual meeting of soil mechanics foundation engineering in December 1962. He elaborated on the study of six special mechanical rock mechanics problems existing in China: the destructive effect of water on loess, soft soil and silt, soil rheology, soil dynamics, rock mechanics, soil physical chemistry and mineralogy— - The importance and research approach. At the meeting, everyone felt very enlightened. We particularly requested Mr. Chen to make a written statement for readers’ reference.
