Abstract

The invention discloses a variable weight-based method for evaluating service performance of a shield tunnel. The method comprises the steps of obtaining monitoring and detection data necessary for evaluation according to a service performance evaluation index system of the shield tunnel; obtaining an initial weight of an index by adopting a confidence index-based expert investigation and survey method; performing variable weight adjustment on the initial weight according to index data; evaluating a structure unit based on a fuzzy comprehensive judgment method; and comprehensively judging an overall service performance level of the tunnel according to a unit structure evaluation level. The service performance of the shield tunnel is subjected to dynamic comprehensive evaluation by utilizing a variable weight method. The value for evaluating the weight of the index not only fully considers knowledge and experience of experts but also can be used to dynamically adjust related weights in time according to actual tunnel conditions, and the influence of a key deterioration index on a final service performance level of the tunnel is highlighted.

Description

technical field [0001] The invention relates to the field of service performance evaluation of shield tunnels during the operation period, in particular to a method for evaluating service performance of shield tunnels based on variable weights. Background technique [0002] With the increase of service life, a large number of existing urban shield tunnel structures that have been put into operation in my country are facing different degrees of damage and aging. Facing the transition from the comprehensive construction stage to the maintenance stage, how to serve the structures of existing urban shield tunnels Performance evaluation, early detection, frequent maintenance, and nip in the bud have become difficult problems for city managers. [0003] It is very important to scientifically and reasonably reflect the service performance level of shield tunnels to guide the safe operation of shield tunnels and the treatment and maintenance of diseases. The existing evaluation meth...
