Title: KEY TECHNOLOGIES OF ROCK ENGINEERING FOR CONSTRUCTION OF XILUODU SUPERHIGH ARCH DAM
Abstract: In each design phase,thorough studies were conducted to explore the key technical issues of rock engineering for the superhigh arch of Xiluodu hydropower project,allowing the physical shape and structural design of the arch to fit the geological conditions of the site.In view of changes in the geological conditions at the foundation of the on the riverbed,the designs of extending foundation surface excavation and dovetailing the body and foundation rock on both upstream and downstream sides were introduced,allowing the arch and foundation to fit each other and improving the stress conditions of the body and foundation.3D geomechanics model test and finite element analysis results indicate that the Xiluodu superhigh arch and its foundation are in good conditions both in construction and operation periods.The monitoring data show that the behaviors of and foundation correspond with regular pattern.Thedigital dam initiative for the Xiluodu project,which is based on the theory of total life cycle,has lent strong support to construction process control and decision-making;this ensures all work conditions in the construction and operation stages meet design requirements,so as to assure the safety and reliability of the arch dam.
