摘要
本文首先对三峡工程二期深水围堰的主要技术问题进行了分析,并简要介绍了围堰各种填料特性和防渗墙材料的研制情况,围堰应力应变状态的数值分析和围堰边坡稳定可靠度分析,大型离心机模型试验的成果等;通过几年来的研究,基本上解决了长期疑惑的一些主要技术难点,所得的成果,不仅对三峡和类似的工程有实用价值,而且对发展学科也起到了推动作用。
In this paper, the complexity and main technical difficulties about the second stage cofferdam is described firstly . Then , brief of the research results on properties of various fills and new impervious materials, the numerical analysis of stress and strain for diaphragm wall, the centrifuge tests, the reliability analysis and others are introduced.Based on those research works, some main technical problems, which were thrown into confusion long, were basically solved or clarified.All research results are not only meaningful for the Three Gorges Project and other analogous projects, but helpful for developing related science field.
