Abstract

Abstract

Most landfills in China are in a long-term service state. Dynamic evaluation on stability of garbage dumps based on real-time monitoring data is of important guiding significance for daily safe operation of landfills. The limit equilibrium method was used to calculate and analyze influences of the existing form of leachate, the liquid level of leachate and the height and position of new rubbish dumps on the stability of landfills. The results showed that the safety factor had a linear relation with the luquid level and the height of the new rubbish dump. The position of the new rubbish dump should be reasonably arranged, which could not be arranged too close to bottoms of landfills and the new rubbish dump should be bulldozed in time to lower the landfill height. In order to ensure the long-term stability of landfills, the drainage system in landfills should be checked in time.
