摘要
实际工程中，当结构较长时，为解决砼的收缩及温度应力，需留设伸缩缝或后浇缝，这对结构施工及按时投入使用都造成诸多不便。本文根据笔者在某花园住宅工程89m长地下室采用UEA补偿收缩砼，一次浇筑，不留后洗缝及膨胀带的工程实际情况，介绍UEA补偿收缩机理，并说明采用UEA的注意要点。
In practice when large size structure is designed, it is necessary to propose expanded joints or post-poured strip to solve problems caused by the stress of concrete shrinkage and temperature. However the proposal will cause delay of construction. In this paper,the author has introduced the principle of UEA com-pensating shrinkage and attentive key-points based on Garden House project with underground structure of 89 meter long. In the construction of Garden House project,UEA has been used t0 compensate the shrinkage of concrete that was poured completely at a time and no post-poured strip and expanded joints are constructed.
