Abstract

The invention belongs to the safety risk perception technology field of building deformation induced by nearby tunnel construction, and specifically relates to a tunnel construction surrounding building safety early warning method based on multi-sensor; the method comprises the following steps: 1, building a multi-layer information fusion model; 2, using grade of membership calculating construction in a cloud model theory to input basic credibility distribution of different risk levels; 3, combining a Dempster rule with a weight average rule to process multi-source evidence fusion and inference containing conflicts; 4, using the Monte Carlo technology to input fuzzy random nondeterminacy of factors through normal state probability distribution symptoms in a measuring process; 5, proposing a risk analysis credibility factor and a global sensitivity analysis index, thus obtaining the final safety risk level. The method can effectively process the nondeterminacy, conflict and error problems in complex decision making, thus obtaining more accurate safety early warning results, and providing very strong accuracy and fault tolerance capability.

Description

technical field [0001] The invention belongs to the technical field of safety risk perception of deformation of adjacent buildings induced by tunnel construction, and specifically relates to a multi-sensor-based safety warning method for buildings around tunnel construction, which can monitor, analyze, and evaluate in a real-time and accurate manner both under the tunnel construction environment. There is a security status of the building. Background technique [0002] In response to urban complex problems such as population growth, space constraints, and environmental degradation, the scale of mechanized construction of subways, highways, pipelines, and utility tunnels in major cities around the world is increasing rapidly. Tunnel excavation in soft soil will inevitably lead to surface settlement, which will cause deformation, rotation, twisting and even irreversible damage to adjacent buildings, especially those with shallow foundations. [0003] At present, the methods f...
