一九八一年九月廿一日至廿四日将在日本东京举行国际软弱岩石力学讨论会. 该讨论会的目的是对世界上的软岩提高新的认识,并讨论工程师们对克服不利地质条件所作的努力在大坝、地下开挖、海底隧道、采矿、核电站、大型悬索桥和传输塔的基础、边坡开挖等方面经常迁到一些不利的地质条件. 软弱岩石表征较显著的力学性状是膨胀、潮解、崩解、蠕变、固结、非线性变形、破 The International Symposium on Weak Rock Mechanics will be held in Tokyo, Japan, from September 21 to April 24, 1981. The purpose of this seminar is to raise awareness of the world’s soft rocks and discuss engineers’ efforts to overcome them. Efforts made in geological conditions often move to unfavorable geological conditions in dams, underground excavations, subsea tunnels, mining, nuclear power plants, foundations of large suspension bridges and transmission towers, excavation of slopes, etc. Weak mechanics of rock characterization Traits are swelling, deliquescence, disintegration, creep, consolidation, nonlinear deformation, breakage
