H型钢+U型钢组合式支护结构施工技术探析OA
Analysis on Construction Technology of H-beam+U-beam Combined Supporting Structure
文中以某建筑工程为例,对H型钢+U型钢组合式支护结构设计及施工进行分析,通过监测技术验证基坑支护结构的变形特性及防水效果,并分析其工程造价及施工周期.结果表明,当开挖至基底侧向变形时,基坑深层水平位移最大值为18 mm;拆撑后最大深层水平位移为32.9 mm,提升了82.7%;施工过程中,坑外地下水位基本保持稳定,最大水位降深为45 cm.同时,HUW工法造价为434 万元,工期仅为2.5 个月.综上,HUW工法具有良好的止水效果、施工效果及显著的经济效益.
Taking a building project as an example,the design and construction of H-beam+U-beam combined supporting structure were an-alyzed.The deformation characteristics and waterproof effect of foundation pit supporting structure were verified by monitoring technology,and the project cost and construction period were analyzed.The results show that when the foundation is excavated to the lateral deformation,the maximum horizontal displacement is 18 mm.The maximum de…查看全部>>
