防渗墙质量缺陷对土石坝渗流控制的影响

以吴家园水库大坝为例,采用渗流有限元分析方法,分析混凝土防渗墙的质量缺陷对大坝渗流控制的影响,比如出现裂缝、墙体渗透系数增大、墙体悬挂等情况。分析结果表明,若防渗墙正常,防渗能满足工程安全要求;若防渗墙出现缺陷,则对坝体各部位的渗透坡降都有很大影响。其中防渗墙出现裂缝的位置比裂缝的宽度对渗流控制的影响更大,防渗墙悬挂比墙体渗透系数增大对渗流控制的影响更大。     

Reservoir volume optimization and performance evaluation of rooftop catchment systems in arid regions: A case study of Birjand,Iran

This study evaluated the performance of rooftop catchment systems in securing non-potable water supply in Birjand, located in an arid area in southeastern Iran. The rooftop catchment systems at seven study sites of different residential buildings were simulated for dry, normal, and wet water years, using 31-year rainfall records. The trial and error approach and mass diagram method were employed to optimize the volume of reservoirs in five different operation scenarios. Results showed that, during the dry water year from 2000 to 2001, for reservoirs with volumes of 200–20000 L, the proportion of days that could be secured for non-portable water supply was on average computed to be 16.4%–32.6% across all study sites. During the normal water year from 2009 to 2010 and the wet water year from 1995 to 1996, for reservoirs with volumes of 200–20000 L, the proportions were 20.8%–69.6% and 26.8%–80.3%, respectively. Therefore, a rooftop catchment system showed a high potential to meet a significant portion of non-potable water demand in the Birjand climatic region. Reservoir volume optimization using the mass diagram method produced results consistent with those obtained with the trial and error approach, except at sites #1, #2, and #5. At these sites, the trial and error approach performed better than the mass diagram method due to relatively high water consumption. It is concluded that the rooftop catchment system is applicable under the same climatic conditions as the study area, and it can be used as a drought mitigation strategy as well.
