Description

BRIDGE LOAD TESTING AND DETECTING DEVICE
TECHNICAL FIELD
The present invention belongs to the technical field of bridge load testing, and particularly relates to a bridge load testing and detecting device.
BACKGROUND ART
A bridge load test is used for verifying the reliability of an overall structure of a bridge in quality and shape, determining the actual strained condition and working condition of a bridge span structure under the action of a test load, evaluating the me- chanical properties and working performance of the structure, ex- amining whether the carrying capacity of the structure can meet the design standard, and comprehending the dynamic property of the bridge span structure and the dynamic performance of control parts under a working load through a dynamic load test and an actual bridge test of inherent modal parameters of the structure, so as to evaluate the strength, rigidity and bearing capacity of a beam.
Bridge deflection is a very important parameter for a bridge structure, which directly reflects the vertical overall rigidity of the bridge structure and is a significant basis reflecting lin- ear variation of the bridge. Bridge deflection is closely related to the bearing capacity of the bridge and the capacities of re- sisting dynamic loads such as earthquakes. Scientific and precise detection means not only is of great significance for detection of the bearing capacity of the bridge and earthquake prevention and disaster reduction of the bridge, but also but also makes it pos- sible to accumulate time experience to perfect the design theory and the construction process of the bridge.
At present, a bridge deflection detector measures dynamic and static deflection curves of the bridge by means of a remote non- contact photoelectric conversion method and organically integrates light path analysis with image acquisition in a breakthrough man- ner. With one target and two lamps as well as dynamic precision range control, the bridge deflection detector is flexibly adapted to various different client and field demands. Powerful processing software can obtain the impact coefficient of the load and the in- ternal force distribution state of the structure from numerical value analysis of the dynamic curve, which is beneficial to deter- mining the weak parts of the bridge and the integrity of the structure. However, the bridge deflection detector itself has the following defects: after the bridge deflection detector is fixed, the base angle needs to be manually adjusted, so that it is trou- blesome to use the bridge deflection detector; and detection data of the bridge deflection detector can only be acquired remotely, the bridge deflection detector cannot be remotely controlled, and the worker needs to arrive at the point of the bridge deflection detector in person to operate the bridge deflection detector dur- ing adjustment every time. To overcome the above defects, a bridge load testing and detecting device is provided.
