| 摘 要： | 采用结构应力监测系统对高大模板在泵送混凝土浇筑过程中的混凝土浇筑侧压力和钢模构件应力进行了现场原位试验研究。揭示了在高大模板工程中泵送混凝土浇筑侧压力的分布规律和主要影响因素。通过对试验数据和与规范公式计算结果的分析,说明了某些规范中混凝土侧压力计算公式的在高大模板工程中的不适应性;研究成果可为改进高大模板设计提供依据。

FIELD EXPERIMENTAL STUDY ON PUMPABLE CONCRETE POURING LATERAL PRESSURE MECHANISM |
| |
| Abstract: | A structural stress monitoring system was used to conduct a field experimental study on concrete side pressure and steel component stress during pouring pumpable concrete by largy formwork.It was revealed that the side pressure distribution law and influencing factors during pouring the pumpable concrete.It was also explained the inadaptability of the calculation formulas of concrete side pressure from large formwork,which were specified in some codes,based on the test data and the analysis of the results by code formulas,which could provide a basis for improving the design of large formwork. |
