Properties Analysis of the Continuous Wall Encountering the Sewage Pipe

While the underground continuous wall of a foundation pit encounters the sewage pipe,the wall need to break off, and the opening produces. To solve the above problems, the paper uses the method of the soil reinforcement and the pile combination, and the soil arch forms between the piles for stress transfer and isolation. By using the finite element, the soil deformation and internal force characteristics of piles are analyzed in detail. The conclusion is that the pile number and soil reinforcement width is the key role to control the soil deformation, and the deformation is smaller along with the greater the scope of consolidation. The measured data shows that the displacement of the opening region in underground continuous wall is less than the calculated value, and the results can be referred to similar projects.
