Abstract: During the construction process of basement beneath the existing buildings, no matter what kind of construction method is applied, it is inevitable to induce the subsidence, sloping and even crack of the existing buildings on the ground, and it will influence the safety and routine use of the existing buildings. With regard to the construction characteristics of basement beneath the office building project of China Industrial and Commercial Bank and based on the investigations into the existing building structures, surrounding environment, construction conditions and operating space, the static bolt-pile deformation control technique is proposed. In order to ensure the safety of the upper structures, and considering the pile-soil-structure interaction, a 3-D numerical analysis is conducted in order to determine the reasonable pile-length and pile-section. The monitoring results show that the settlement of the structures during the construction process is in good accordance with the calculated results. The deformation control technique is reasonable, the construction measures are appropriate, and the structures are in the range of allowable safety.
