无空间支架支撑模板稳定性分析

Stability analysis of formwork without space support

针对高速公路加宽过程中通道墙单侧加厚施工时无空间支架支撑模板稳定性问题。采用数值计算与现场试验验证相结合的方法,研究了支撑模板的植筋钢筋间距对模板稳定性的影响,确定了合理的植筋钢筋间距并进行了现场应用。结果表明,提出的方法合理、实用,具有良好的社会经济效益和推过应用价值。

In view of the stability of the formwork without space support during the unilateral thickening of the channel wall in the process of highway widening,the influence of the spacing of planting reinforcement on the stability of the formwork was studied by combining the numerical calculation and field test verification,and determines the reasonable spacing of the planting reinforcement and carries out the field application.The results show that the method proposed is reasonable and practical,and has good social and economic benefits and application value.
