摘要
防渗帷幕在很多国家得到较广泛的应用 ,但深度超过 35m较少。防渗帷幕其施工目标参数控制难度大 ,而且深度增加导致难度更大。因此施工目标参数对施工影响起关键决定作用。究竟应如何确定合理的目标参数 ,即保证防渗帷幕的工程作用 ,又不会增加施工难度和工程造价 ?通过土力学基本理论分析 ,并针对各影响因素进行多工况比较计算 ,然后对比现行相关规程规范 。
Super-deep anti-seepage purdah is used very few and mainly in hydraulic and bridge engineering. It is very difficult to control its parameters, which are very important to the construction. How to determine those parameters that not only insure the engineering effect, but also affect the cost. Based on the basic theory and calculations, and compared with the related law, the appropriate parameters are put forward, which are also proved by certain construction.
