| Abstract: | This paper studies the combination of innovative pre-stressed steel support and stiffing piles. The transfer mechanism for the supporting connection at the juncture of the two supports is analyzed. A checking method is also proposed to check the foundation strength, the foundation bear/ng capacity, the connecting bolt at the support of the sidewall foundation of the bearing foundation. Finally, the mouitozing data derived from the two practical engineering projects of strength and deformation shows that the calculation method proposed in this paper can meet the demands of the actual projects. Thus, it is critical to popularize the combination of the two supporting forms, improve the safety of the foundation pits, and economize on the foundation pits. |
