Abstract：
Internal support conversion technique is adopted to dismantle the internal support in segments in the foundation pit project of six starting plots in Yujiapu Financial District, Tianjin. The internal support conversion construction of Plot 15 is taken as an example to research internal support conversion design and construction technique, construction technique of force transmission component and internal support dismantle method, etc. The difficulty in one-shot dismantlement of internal support is successfully solved, not only satisfying the requirements for overground construction of underground structure, but also ensuring the foundation pit safety and realizing harmony between schedule and safety.
