基于QC小组无粘结预应力混凝土内支撑研究

Research on Unbonded Prestressed Concrete Internal Support Based on QC Team

岩土工程不仅蕴含着深刻的科学原理,而且依赖于不断更新的工程实践。基于QC小组活动始终提倡和坚持“小、实、活、新”的发展方向,强调发挥主观能动性,通过研究在传统的普通钢筋混凝土内支撑系统中采用无粘结预应力技术,运用质量管理小组中的管理技术创新基坑混凝土内支撑支护,并形成一定标准化,可为今后提高基坑工程支护结构设计水平提供参考。

Geotechnical engineering not only contains profound scientific principles,but also depends on constantly updated engineering practice.Based on QC team activities,we always advocate and adhere to the development direction of “small,practical,flexible and new”,emphasizing the exertion of subjective initiative.By studying the use of unbonded prestress technology in the traditional ordinary reinforced concrete internal support system and the management technology in the quality management group,the concrete internal support of foundation pit is innovated and standardized.It can provide direction for using QC team activities to improve the design level of foundation pit engineering support structure in the future.
