How to accurately determine the mechanical parameters of rockfill is one of the key issues of concrete-face rockfill dams. Parameter back-analysis using internal or external monitoring data has been proven to be an efficient way to solve this problem. However, traditional internal or external monitoring methods have limitations in efficiency and long-term monitoring. In this paper, the displace...

In view of the problem insufficient storage capacity original landfill site, it is a very economical and effective way to use horizontal, longitudinal composite extension garbage dam with geotextile reinforced earth dam. this paper, types dam, technology, reinforcement method stability are introduced discusses advantages disadvantages retaining, construction technology analysis influencing fact...

pressurized injection operation means the pressurized injection of a liquid or solution into pore of a mass of soil or stone and/ or cavity between them and built structures. the injected mortar mustconstitute a soil and/ or jel- like matter inside the cavites, and/ or the operations of the injection must cause sedimentation of the solid matter suspending in these cavites. the primary purpose o...

The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability analysis and deformation calculation are presented. Methods for calculation of deformation of post liquefaction stage are also briefed.

The study of the reliability and safety constructed earth-fill dams comparison with their design calculated data makes it possible to improve structures methods calculation substantiation these structures. This work aims filtration dam Channel water reservoir Tuyamuyun hydroelectric complex (THC) on Amu Darya River, which was put into exploitation in 1984. Field studies were carried out accordi...
