Description
Technical field
The present invention relates to a kind of civil engineering detection field, sensing technology, information engineering, mechanical engineering, artificial is combined
Intelligence multidisciplinary, more particularly to a kind of bridge security cruising inspection system and diagnostic method based on tcm methods.
Background technology
Bridge is the chief component of road traffic, once built up and come into operation, in addition to building in its service phase
Material self performance can constantly degenerate it is outer, also inevitably by vehicular load, environmental load, earthquake load, it is artificial because
The repeated action of element etc., generates structure different degrees of damage, and material aging and damage accumulation cause structural behaviour constantly to move back
Change, burst may be caused partly or wholly to destroy disaster.Therefore economical, conveniently, it is credible, holographic and identical future developing trend
Bridge security testing equipment and diagnostic method are the common pursuits of domestic and abroad bridge circle.
In the prior art, it can substantially be divided into regular safety inspection for the safety inspection of bridge structure, inspect periodically
And special examined.Periodically inspection side and special examined are often referred to by equipment special to infrastructure architecture object periphery to agent structure
It carries out near viewing and test, this inspection is considered effective but commonly required costly and can influence basis
The normal use of facility, it is primary that detection frequency is generally 2-6；For ensure it is adjacent inspect periodically twice between bridge operation peace
Entirely, it is desirable that monthly at least carry out the regular inspection of a bridge, be usually using manually patrolling on works on the implementation
Distant surveillance is made to works depending on or with telescope, because by detection methods, practitioner quantity and quality limited, only with
Perceptual knowledge, lacks quantifiable data information, it is difficult to which the safe condition for promptly and accurately knowing works causes the frequent of structure
Property inspection is mostly useless.
Currently, the application that the structure Long Period Health Monitoring system based on sensor is monitored in span bridge health is more next
It is more, by the displacement meter of substantial amounts, strain gauge, dipmeter, thermometer, hygrometer, accelerometer, Crack Monitoring, weighing machine
Equal senser elements are directly installed on works, to realize to the quiet of structure, dynamic characteristics variation and damage monitoring.Such prison
Survey means are substantially the direct measurement of one system of a structure, and advantage is the possible full-time information for grasping structure, but it has system
Construction cost of uniting is high, labor intensive financial resources, and returned data confidence level is high, data drifts and noise phenomenon are serious, magnanimity number
According to being difficult to handle, the shortcomings of the limited information being only capable of on measuring structure at limited sensor installation point, and contained by the system
The service life of original paper is monitored generally in 5-10, and the normal use time limit of bridge is in 50-100, which is difficult to
Meet the long-time service demand of monitoring structural health conditions, replaces monitoring original paper and maintenance system normal work difficulty is big, costly.
In conclusion the method for currently used bridge structure safe monitoring, means, equipment, personnel and effectively detection
For the frequency far from the actual demand for meeting infrastructure, therefore for the bridge security inspection having a large capacity and a wide range, there is an urgent need to find
It is a kind of it is economical, conveniently, credible, holographic and identical future developing trend bridge security testing equipment and diagnostic method to be to have conscientiously
Effect holds bridge security state, and disaster prevention accident occurs.
