Dynamic design for high slope treatment for left bank underground power house intake of Longtan hydroelectric project

摘要

The high slope treatment for left bank underground powerhouse intake of Longtan hydroelectric project is one of the important technical issues for the project construction. The excavation and strengthening scheme was determined after pre-exploration, lots of scientific experiments and stability study having been carried out. Furthermore, emphasis was placed on strengthening dynamic design and control for the project in the period of the construction. This paper gives a brief introduction for the slope geological conditions, outline of the design general situation, dynamic design concept and procedures and the dynamic design and control for the project in the construction practice.
