Abstract
Abstract
The underground pipe gallery is a symbol of modernization and intensification of urban construction. Domestic research on the deformation of underground pipe gallery started late and has not yet formed a unified standard. Based on the deformation requirements and deformation control standard of the internal pipeline of the pipe gallery, the longitudinal deformation control standard of the integrated pipe gallery is preliminarily established. The main conclusions are as follows: Based on the deformation requirements of the underground pipe gallery, the equation for calculating the allowable value of the longitudinal radius of curvature of the pipe gallery is proposed. Comparing the safety standards of various types of inlet pipelines, the longitudinal deformation allowable value of the pipe gallery is given. At the same time, the influence of surface load on the deformation of pipeline gallery is analyzed by theoretical analysis and model test, and the theoretical and experimental results are compared. The results indicate that theoretical calculation features accuracy and practicality.
