混凝土重力埙的抗滑安全稳定,是一个十分重要的問題。过去国外有很多坝由于基础不止缺乏应有的抗滑安全度而失事,以致造成生命、財产上的严重损失。但是,另方面,如果基础良好,坝体断面选择过大,又将增加工程量,造成投資上的浪費。过去,国外水利水电工程界对坝体抗滑稳定問題的研究,已进行了数十年,取得了一些成果。茲将他們的試驗研究情况,分成試驗规模和分析研究两方面介紹于后,以供参考。
The anti-slide safety and stability of concrete gravity 埙 is a very important issue. In the past, many foreign dams crashed due to the lack of security on the basis of their anti-skid safety. As a result, life and property suffered serious losses. However, on the other hand, if the foundation is good, the section selection of the dam body is too large, which will in turn increase the construction volume and result in the waste of investment. In the past, foreign water conservancy and hydropower engineering on the stability of the dam anti-skid research, has been carried out for decades, and achieved some results. We hereby divide their experimental research into experimental scale and analytical study for reference later.
