中国水利学会主办的大坝软基处理学术讨论会,于1982年10月27日至11月1日在陕西省武功召开。会上交流的经验很多,现结合在我省适宜推广的先进技术择要介绍于下: 一、关于混凝土防渗墙方面混凝土防渗墙在我国水利工程中应用发展迅速,目前全国已建成60道混凝土防渗墙,总截水面积达40万平米。特别近几年来,不但在基岩表面的岩溶通道中,还在岩基以上堆积有大量坚硬孤石的地层中以及在水下抛填未经压实的严重漏浆的砂砾石层中均建成了混凝土防渗墙。所有这些都标志着我国混凝土防渗墙的施工技术有了很大提高。
The Chinese Society of Hydraulic Engineering hosted a symposium on dam soft foundation treatment, which was held in Shaanxi Province from October 27 to November 1, 1982. At the meeting a lot of experience in exchange, is now combined with the promotion of advanced technology in our province choose to be introduced in the next: First, on the concrete cutoff walls Concrete cutoff wall in China’s water conservancy projects in the rapid development of the application, at present, the country has built 60 Concrete cutoff wall, the total water cut-off area of 40 million square meters. Especially in recent years, not only in the bedrock surface karst passage, but also in the rock over the accumulation of a large number of hard rock boulder formations in the ground and under water thrown filled uncompacted serious leakage of gravel layer are built Concrete cut-off wall. All these marks the construction technology of concrete cutoff wall in our country has been greatly improved.
