In the final disposal site, bentonite mixed soil layer is often used as a leachate battier.
In this study, we established a model BMS layer having a thickness of 50cm, the experiment was carried out under the conditions that changed several depths of local subsidence and the presence or absence of GeoNet.And I understand the performances of BMS leachate barrier layer were deformed.As a result, when the crack width of the BMS surface occurs more than 2mm, was confirmed that the performance of BMS water barrier is compromised.
In addition, crack of 2mm or more, was confirmed when the subsidence of more than 5cm occurs for no GeoNet. When you install the GeoNet, it was confirmed when subsidence 10cm or more occurs.
