| Abstract: | Processing the barrier met in the toundation pit construction when rebuild in the existed building site is one of the construction difficulty. Aceording to the Nankai center project in financial street in Tianjin, this paper introduces several processing methods of underground obstacles in the construction of foundation pit, and makes a brief analysis. Practice shows that these methods ean ensure the construction of engineering pile, support structure and the earth excavation succ.essfully, and can protect the safety of surrounding environment, provide the referenee for the future similar engineering construction. |
