In order to avoid the overallcarryingsoil failure in shallowburied rectangular pipe jacking project, the causes for the actual overallcarryingsoil failure are analyzed based on the existing research results and the theory of the overallcarryingsoil, by taking an underground parking lot project for example. Firstly, by analyzing the characteristics of the overallcarryingsoil failure phenomenon of the project site, it is concluded that the adjacent tunnel construction, attitude adjustment, pipe jacking machine stop, and antifriction mud failure are the main causes. And then the overallcarryingsoil treatment measures, i.e. grouting pipeline investigation, pileloading at the carryingsoil position in front of the cutterhead, borehole water injection at the carryingsoil position, and partition wall, etc.〖KG-*3〗, are adopted and described, respectively. Finally, it is concluded that the phenomenon of overallcarryingsoil can be effectively avoided by reducing the friction coefficient of soil on the pipe under the premise that the soil resistance around the pipe cannot be changed.
