Abstract
With the large-scale application of urban comprehensive pipe gallery in China, it is an urgent engineering problem that how to adopt appropriate technical schemes for the foundation of comprehensive pipe gallery under different geological conditions. First of all, this paper starts from the unique stress condition of the comprehensive pipe gallery, through the analysis of the change of the stress on the foundation soil, it comes to the conclusion that the stress on the foundation soil becomes smaller after the completion of the comprehensive pipe gallery structure, and further analyses the influence of the buried depth and section size on the stress change of the foundation soil. Then, according to the foundation treatment scheme of the comprehensive pipe gallery in the collapsible loess area, some optimized suggestions and ideas are put forward, in order to provide more economical and simple foundation treatment measures for the construction of the comprehensive pipe gallery in the future.
