  • The static bolt-pile technique is firstly applied to the construction of basement of the existing buildings. A new layer of 3.6 m-underground garage is built beneath the existing buildings successfully, and the secondary development of underground space beneath the existing buildings comes true. Based on an office building project of China Industrial and Commercial Bank, the design scheme and key techniques of the construction of basement are proposed. The monitoring results show that the largest uneven settlement between columns of the existing buildings is only 4.93 mm, and it meets the relevant national standards. The settlement of the surrounding roads is small, and the settlement rate is gentle. So the influence of the construction on the existing structure and surrounding roads is very small. The application of the static bolt-pile technique to the project is successful. It provides a good example for the promotion of similar projects and the secondary development of urban underground space.
