A whole process simulation calculation is done for the temperature field and creep thermal stress field of Baise RCC gravity dam from construction stage to operation stage under summer shutdown scheme by using 3D FEM relocating mesh method.

Concentrated on the questions in heightening of dams, and focused on the practice of heightening of Danjiangkou dam, questions in heightening of concrete gravity dams were systematically studied such as connection of new and old concrete, temperature field, and thermal creep stress field by using of large F.

But temperature field and thermal creep stress of the roller comp.

Shrinkage and creep of high-strength lightweight aggregate concrete;

The sidewall fracture of the shaft and the creep of concrete;

Long-period contraction creep forecast of concrete based on short-period test;

Vertical deformation calculation of the high-rise concrete structure resulted from creeping

Based on the background of Maocaojie Arch Bridge, a test study was made of the creeping of high-performance concrete by simulating the actual concrete percentage and sectional stress state of an actual section.

In order to understand the factors influencing the creeping of concrete with compound ultra-fine fly ash (CUFA), the creep behavior of C50 concrete with CUFA and C50 ordinary portland concrete were tested by parallel experimental methods.
