In geomembrane rockfill dam reservoir anti-seepage, geomembrane is an important anti-seepage material. The use of geomembrane can significantly reduce the maintenance cost of the dam body and extend the service life of the dam body. 

First of all, the laying of geomembrane is a key link in the anti-seepage of geomembrane rockfill dam reservoirs. During the laying process, the integrity of the geomembrane must be ensured to avoid problems such as damage or cracks. At the same time, the overlap length and welding quality of the geomembrane also need to be strictly controlled to ensure its anti-seepage effect. After the laying is completed, a weld pressure test needs to be carried out to check the sealing and anti-seepage performance of the geomembrane.

Secondly, the selection of geomembrane is also an important factor in the anti-seepage of geomembrane rockfill dam reservoir. The appropriate geomembrane thickness needs to be selected based on the actual situation of the reservoir and anti-seepage requirements.

In addition, in the anti-seepage of geomembrane rockfill dam reservoirs, the compaction degree of the dam body is also an important factor affecting the anti-seepage effect. During the construction process, the compaction of the dam body needs to be strictly controlled to ensure that it meets the design requirements. At the same time, the dam body needs to be inspected and maintained regularly to detect and deal with existing leakage problems in a timely manner to ensure the safe operation of the reservoir.

In the future development, the dam geomembrane can be monitored and maintained in real time, and existing reservoir geomembrane leakage problems can be discovered and dealt with in a timely manner, reducing the leakage loss of the reservoir, ensuring the normal operation of the reservoir, and improving the safety and stability of the reservoir. Further promote the continuous progress and development of geomembrane rockfill dam reservoir anti-seepage technology to meet the continuous needs of China's water conservancy project construction.
