摘要
以某地铁桥墩混凝土施工中立柱模板坍塌事故为例,指出92规范中混凝土侧压力计算公式的不足之处;作者通过对现行英、美施工标准相关内容的介绍与分析,提出在缺乏有效试验数据支持的情况下,高大竖向模板混凝土侧压力计算应采用静水压力公式,以确保模板方案设计与施工的安全可靠。
According to collapse accident of column templet in concrete construction of iron bridge pier, defects of calculation foimula of concrete lateral pressure in the code of 1992 are pointed out. After introduction and analysis on relevant content in applicable British and American construction standards, it is proposed that hydrostatic pressure formula shall be adopted for calculation of lateral pressure of high and larger vertical concrete templet under condition where there is not enough effective testing data, so as to guarantee safety and reliability of design and construction of templet.
