Study on Stress Field of Concrete with Large Foundation Defects under Fast Casting Condition

摘要

In the process of concrete dam foundation treatment, it is often encountered that the foundation defects are beyond the expected exploration. In order to ensure the quality of the project and the progress of the construction period, the stress field of the mass concrete in the foundation pit under the condition of fast filling is studied by numerical simulation method. Based on the calculation results and engineering experience, some comprehensive measures of temperature control and crack prevention are put forward: pipe cooling + reasonable angle arrangement of anti-sliding anchor bar + reasonable position of the limit of crack reinforcement layout. Which can provide some reference for solving similar engineering problems.
