Numerical Results of Creep Parameters Characteristics of Xiluodu Arch Dam Concrete It is crucial for super dam engineering that the great amount of temperature creep stress can be cut down efficiently during the massive concrete pouring process.
(3) (4) Conclusions Super dam engineering must control the accumulation of temperature creep stress which may incur overwhelming destruction of massive concrete blocks.
Here introduced are two primary functions, i.e., HydroChina Chengdu Engineering Corporation model and Yangtze River Scientific Institute model.
