Numerical Simulation of Formwork Pressure While Pumping Self-Compacting Concrete Column

【Abstract】： In view of the variation law of formwork pressure is not clear when pumping self-compacting concrete from the bottom up. The filling process of column formwork with self-compacting concrete was numerically simulated. The accuracy of the numerical simulation was verified by comparing with the test data， and then the variation of formwork pressure during column formwork pouring was investigated.

【Key words】： CFD；formwork pressure； self-compacting concrete

目前，大多数确定模板压力的规范[1]都是针对普通混凝土浇筑工艺制定的，有些不适用自密实混凝土的浇筑。（剩余3024字）
