关于超危模板支撑工程简易判断与计算的探讨

Discussion on Simple Judgment and Calculation of Super-dangerous Formwork Supporting Engineering

在坍塌事故占较大及以上事故比例45%的情况下,超危模板支撑工程的预判、方案计算与验算显得尤为重要。基此,通过模拟计算确定超危模板支撑工程简易判断标准,并分析4个现行相关规范及标准的差异,探讨超危模板支撑的荷载取用及组合的计算依据选择和立杆稳定性计算依据选择。

In the case that collapse accidents account for 45% or more,the prediction,scheme calculation and check calculation of the over-dangerous formwork support project are particularly important.This paper will determine the simple judgment standard of the overdangerous formwork support project through simulation calculation,and discuss the calculation basis selection of load acquisition and combination of the over-dangerous formwork support and the calculation basis selection of the vertical pole stability by analyzing the differences of the four existing relevant codes and standards.
