Safety supervision on the exit slope of right waterway of Longtan Hydropower Station during construction period

It is difficult to forecast and judge the stability of slope and its support effectiveness because the complex geological conditions and diversified deformations. But all-round field supervision and analysis can give strong support to it. According to the monitoring design, results and excavation support of the exit slope of right waterway of the Longtan Hydropower Station, we analyze the slope stability and its deformation, and initially estimate the effectiveness of the slope reinforcement. Some conclusions were made as follows. The monitoring of the exit slope of right waterway has provided the construction and operation of slope with reliable basis. The slope reinforcement is relative stable. But it is necessary to conduct further monitoring and maintenance.
