| 摘 要： | 根据渗流计算理论并利用有限元计算方法,着重研究Hardfill坝在不同透水性坝基下的渗流场规律,并将其与设置各种不同防渗排水措施后的Hardfill坝渗流场规律进行比较,以便确定合理的防渗排水体系.通过变化坝基的渗透系数模拟各种不同透水性坝基.将计算结果整理成流网图和特征点渗透坡降图,为整体把握Hardfill坝的渗流特性和Hardfill坝的进一步研究工作打下基础.

| Abstract: | Based on seepage calculation theory and by using finite element method,the laws of seepage flow field under dam foundations with different permeabilities are studied mainly;and it is compared with the dam foundations with different seepage prevention and drainage measures so as to ascertain the appropriate seepage prevention and drainage system.Different permeabilities dam foundations are simulated by change of permeability coefficient of the dam foundation.The pictures of flow network and seepage gradient are obtained from the calculation results;and they provide references for grasping the seepage property of the Hardfill dam as a whole and are helpful to the dam's further research. |
