本文是针对本刊1981年第1期发表的陶景良同志的《混凝土防渗墙墙段间接缝夹泥的危害、成因及防止措施》一文而写的。文中介绍了某水电站防渗墙开挖出来后所观察到的实际情况,并就陶景良同志的某些看法提出商榷意见,同时介绍了国外有关的经验资料。我们认为这对促进防渗墙技术的发展是有益的,特发表供读者研究参考。 This article is written for the article entitled “Dangerous, Causes and Preventive Measures of Interlocking Clamps in Concrete Diaphragm Walls” published by the first issue of 1981 by Tao Jingliang. This paper introduces the actual situation observed after the seepage prevention wall of a hydropower station is excavated, and puts forward some opinions on some views of Comrade Tao Jingliang. At the same time, it introduces the relevant foreign experience data. We think this is useful for promoting the development of cutoff wall technology, especially for readers’ reference.
