In addition to save materials, reduce cost, increase excavation work space and reduce the construction time, it can get the secondary compensation of prestress to control deformation of foundation pit by retensing the Fish-Bellied Beam construction in the process of earthwork excavation, so as to ensure the safety of foundation pit[3].
Fender post is translated into underground continuous wall according to principle of equivalent stiffness[7], and the thickness is 0.6m.Assuming fender post is a kind of linear elastic material, E=20GPa.The contact between pile and soil is simulated as an interface[8].
