The “pile–wall” structure, which considers conventional temporary retaining piles as parts of the underground structure in the normal working stage, has been practiced, but there are insufficient studies on the optimization of the design of the “pile–wall” structure and the influence of various factors on the structural stresses and deformations. In order to analyze the factors affecting the stresses and deformations of the “pile–wall” structure, the numerical simulation of the “pile–wall” structure was carried out with the help of finite element simulation software Plaxis 3D through the excavation of Wuhan Optics Valley Center City Distributed Energy Project. The research of stresses and displacements on the “pile–wall” structural under the influence of different factors were carried out. The results show that the number of pile–wall connection nodes, the pile–wall thickness ratio, and the pile–wall stiffness ratio have influences on the stresses and deformations of the “pile–wall” structure. The number of connection nodes which is 4, the pile–wall thickness ratio which is 1 : 0.3, and the pile–wall stiffness ratio which is 1 : 1 are the most reasonable for the deformation and force of pile–wall structure in the project. The research results have good reference and guiding significance for the actual “pile–wall” excavation engineering structure, and the purpose of energy-saving and consumption-reducing construction can be achieved by seeking the reasonable values of the three and optimizing the construction program. |
