软土地基文物建筑地下空间开发的关键技术与应用
Key techniques and application of underground space development underneath heritage buildings in soft soil
摘要
Abstract
With rapidly increasing demands for urban underground space construction in the course of city renewal process,it needs not only to develop the underground space surrounding the existing building,but also to utilize the space underneath the building.An I-shaped heritage building renovation project on soft clay in Shanghai using a series of underground space development techniques,which includes settlement-controlling pile foundation underpinning,retaining and protection for excavations combined with the underpinning structure,synchronous jacking-up of the I-shaped building and the seismic isolation design,are presented.By excavating downwards and jacking-up the building upwards,during which the structural loading is transferred to the newly-constructed pile foundation in three stages,a basement has been constructed underneath the heritage building.The analysis of monitoring data during the implementation of the project shows that the total and the differential deformation of heritage buildings are both within the permissible range of the project,and satisfy the protection requirements of the heritage building.关键词
