Abstract: Aiming at the construction safety risk control problem of network construction project in underground space, five network methods including adjacent extension and construction, connection between existed structures extension, vertical direction extension,enlargingexistingunderground extension and multidirectional extension were proposed. The risk characteristics of network construction project were studied and analyzed. In planning and design stage, the safety planning and design methods and pre-redundancy design were established. In construction stage, pre-planning and design methods of quality evaluation,verification and feedback were constructed. The new planning and design technology could guarantee the safety in the whole process of network construction project. Based on the hierarchical control of the interference level, the safety pre-control measures for the four elements in construction projects including the extended structure, the existing structure, the ground and the surrounding environment were put forward. The new construction safety monitoring index system was given so that the safety risk prevention and control could be fully implemented in the construction process. The researched results provided theoretical guidance and technical support for the planning and design and safe construction of underground space network construction project.
