应国际岩石力学协会和巴西岩石力学协会的邀请,中国大坝委员会派出代表团参加了在巴西里约热内卢举行的有关坝基岩石力学国际讨论会。会议于1978年9月26日至29日召开,共有23个国家的471名代表参加。会议讨论了教学与科研组织、坝基岩体特性和分类、坝基分析和设计方法、开挖爆破对结构和岩石的影响以及坝基和边坡处理等五个方面的问题。通过这次会议看出,随着岩石力学的发展和大坝工程建设的进展,坝基岩石力学正在逐渐形成一门比较独立而有一定特色的分支技术学科。由于会议时间短,讨论的问题未得出一致的结论,主要是交流了学术观点,指出了今后的研究方向。本文系我代表团回国后的汇报材料,现发表供有关部门和同志研究参考。发表时本刊略有删节。
At the invitation of the International Association of Rock Mechanics and the Brazilian Association of Rock Mechanics, the China Dams Committee dispatched a delegation to attend the International Symposium on Rock Mechanics of Dam Foundation in Rio de Janeiro, Brazil. The meeting was held from September 26 to 29, 1978, with a total of 471 delegates from 23 countries. The meeting discussed five issues of teaching and research organizations, the characteristics and classification of dam foundation rock mass, dam foundation analysis and design methods, the influence of excavation blasting on structures and rocks, and dam foundation and slope treatment. Through this meeting, we can see that with the development of rock mechanics and the progress of dam construction, the rock mechanics of dam foundation is gradually forming a branch technology discipline that is relatively independent and has certain characteristics. Due to the short meeting time, the issues discussed did not reach the same conclusions, mainly the exchange of academic point of view, pointed out the direction of future research. This article is my report after the return of the delegation material, is now published for the relevant departments and comrades for reference. At the time of publication, there were some abridgement
