With the development of urban construction, deep large pits are often located at intensive underground structure area, and the utility pipe tunnel within various pipelines is the lifeline engineering of urban environment. Thus, there is the very necessary practical significance to research on utility pipe tunnel influenced by adjacent deep Excavation. Using large finite element software ANSYS, we analysis the problem with the deep foundation pit, support system, the soil around and adjacent tubes as an entirety. In considering of the mutual interaction between support structure and soil, as well as the element birth-death technology and restart analysis technology, the deep foundation pit mode is simulated and analyzed according to the actual construction process, including the gravity initial stress analysis and the simulation analysis on the each layer soil excavation. After simulation analysis the level of utility pipe tunnel’s horizontal and vertical displacement environment in different affecting factors and reinforcement measures, it is concluded that the law of utility pipe tunnel’s horizontal and vertical displacement, further the reasonable economic measure is put forward to protect the safety of the utility pipe tunnel. Therefore the conclusion has certain reference value for designing the foundation pit construction and the protection measures on the adjacent utility pipe tunnel.
