摘要
本文采用室内模拟现场实际情况的试验方式,分析平原水库在采用土工膜防渗情况下的土体初始含水率对膜下气场的影响。结果表明:膜下土体初始含水率对膜下气场有明显影响,并在含水率为20%情况下,膜下气场产生达到极致。根据分析结果,对平原水库土工膜防渗排气方案提出建议。
This paper,with experimental way of indoor simulation of the actual situation ,analyzes the impact of plain reservoir in the initial soil moisture content using geomembrane case of the film under the gas field.The results show that:the initial moisture content of soil under the membrane had a significant effect on the film under the gas field,and in the case of a moisture content of 20%,the film produced under the gas field to the extreme.According to the analysis results ,recommendations are put forwards for the plain reservoir geomem-brane exhaust program.
