【摘    要】：針對自密實混凝土自下而上泵送澆筑過程中，模板壓力變化規(guī)律不明確的問題，對自密實混凝土自下而上填充柱模板的過程進行了數(shù)值模擬，通過與試驗數(shù)據(jù)對比驗證模擬的準(zhǔn)確性，進而探究了柱模板澆筑過程中模板壓力的變化規(guī)律。

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，大多數(shù)確定模板壓力的規(guī)范[1]都是針對普通混凝土澆筑工藝制定的，有些不適用自密實混凝土的澆筑。（剩余3024字）
