燃煤电厂贮灰场防渗通常采用的是铺设防渗复合土工膜,工程投资高,当灰场库区植被良好时还会破坏原生植被.根据某工程灰场地层的性质、结构,采用水利部科技创新计划项目“污染物在低渗透性土体中迁移的离心模型试验研究(SCX2002-12)”的成果,通过渗流计算分析和污染物迁移分析,取消了防渗复合土工膜,优化了防渗设计方案,对其他灰场防渗设计具有参考价值.
In coal-fired power plant ash seepage seepage control is usually used in laying impermeable composite geomembrane, engineering investment is high, when the ash field reservoir vegetation is good, it will destroy the native vegetation.According to the nature of a project ash field stratum, the structure, the use of water Ministry of Science and Technology Innovation Project “the results of the centrifuge model test study on the migration of pollutants in low permeability soil (SCX2002-12) ”, through the seepage calculation and analysis of pollutant migration analysis, the impermeable composite geomembrane was canceled, Optimized seepage prevention design scheme, has reference value for other seepage prevention design of ash field.
