Abstract

The invention discloses a method of risk ranking control of crossing engineering of urban rail transit. The method comprises the following steps of collecting related data and factors of design and construction; establishing an influence rank according to the influence degree of the construction; determining a specific area coverage of the influence rank according to the specific construction manner and range; analyzing through the influence area coverage determined in the step S3 and the related data and factors of design and construction, and establishing risk ranking; controlling and monitoring the risk ranking corresponding to different construction manners. According to the technical scheme of the invention, safety operation of the existing urban rail transit is guaranteed, the risk of the crossing engineering is effectively controlled, and the scientific management and the decision level for risk control of the crossing engineering of the urban rail transit are improved.

Description

technical field [0001] The invention relates to the field of urban rail transit crossing projects, in particular to a risk classification control method for new construction crossing urban rail transit projects. Background technique [0002] Crossing urban rail transit projects refer to construction projects that cross or adjoin rail transit lines and their facilities and affect their safety. Various projects of traffic lines and their facilities. The crossing project will cause the existing structure and track to deform or even exceed the limit, which will bring great safety hazards to the normal operation of urban rail transit projects. In order to better control the risk of the crossing urban rail transit project, it is urgent to identify the risk of the crossing project before the construction of the crossing project. [0003] The research on safety risk identification of crossing projects in my country started relatively late. Due to the variability of stratum condit...
