摘 要:依据郑东新区高支模架现场试验结果,对地基土土压力及变形进行了监测,结合数值模拟及分层总和法理论计算结果对比高支模架不同位置的土压力与地基土变形,分析三者之间的数值差异,并对差异原因进行了分析,提出了在实际工程中应考虑应力集中保证一定的安全系数的观点,为高支模板及后续现浇结构设计施工提供了实测依据。
Abstract: Based on the field test results of high scaffolding in Zhengdong New Area, foundation pressure and deformation were monitored. Combined with the results of numerical simulation and layerwise summation method, the results of high scaffolding for different positions of earth pressure and soil deformation were compared, numerical difference and cause of the three were analyzed. The results showed that, considering the stress concentration and using safety factor in the practical construction work can provide experimental basis for high scaffolding and subsequent cast-in-situ concrete structure design and construction.
