摘要: 溧阳抽水蓄能电站上水库地质条件复杂,库盆防渗体系由于库底填渣厚度变化大,不均匀沉降较大,设计选定防渗材料适应不均匀变形能力强的HDPE土工膜作为上水库库底防渗体系;在减少渗漏损失的同时,可以降低工程施工难度。主要介绍了土工膜防渗方案的设计及应用,包括防渗层材料的选择及设计、土工膜周边连接设计、土工膜施工工艺等。

Abstract: The geological condition of the upper reservoir for Liyang Pumped Storage Power Station is complex. Because the thickness of filled landfill at the bottom of the reservoir varies rapidly and the differential settlement is large, the HDPE geomembrane is adopted as the material of reservoir bottom seepage prevention system owing to its flexibility to unequal transformation, which reduces the seepage loss and make the construction be easier. The design and application of geomembrane seepage prevention system are introduced, including selection and design of materials for seepage prevention layer, surrounding connection design of geomembrane, construction method of geomembrane etc.
