APPLICATION OF UNDERPINNING TECHNOLOGY IN A BASEMENT REBUILDING PROJECT
-
摘要: 随着铁路工程的飞速发展和跨越式的革新,推动了铁道建筑、结构设计理念不断创新。武昌火车站房大跨度楼盖采用了双向钢-混凝土组合楼盖结构体系,保证其舒适度是很有必要的。通过动力特性和行走激励时程反应分析表明,武昌站大跨度楼盖设计满足舒适度的要求。Abstract: Through a basemen trebuilding and reinforcement project, this article introduced the application of Underpinning technique in a basement rebuilding project from theoretical analysis and engineering practice. First of all, this article disscussed the result of underpinning project, lift-up force and lift-up displacement in rebuilding design; then introduced application of ground treatment technology in this project; at last,evaluated the effect of the rebuilding project by localm onitoring of the structure displacement and sedimentation observation of building in later period.
