摘　　要：为提高混凝土模板侧压力计算的准确性,设计了基本参数试验,研究混凝土和模板之间的摩擦系数μ与侧压力折减系数K的时变特性对模板侧压力的影响。基于分层总和法建立了混凝土模板侧压力计算模型,推导修正计算式并进行验证分析。结果表明考虑时变特性的分层总和法修正式能较好地预测模板侧压力值。To predict the lateral pressure of formwork more accurately,an experiment aims to investigate the influence on lateral pressure of formwork caused by the time-varying characteristics of friction coefficientμand reduction coefficient K was conducted.Based on the method of stratified summation,a model for calculating the lateral pressure of formwork was established,the modified calculation formula was deduced and verified.The results showed that the modified formula that considering the time-varying characteristics of key coefficients could perform well in predicting the lateral pressure of formwork.
