Embodiment Construction

[0054] When monitoring large deformations, conventional contact displacement sensors are difficult to continuously track and monitor, while non-contact displacement sensors have high cost and poor real-time performance, which may easily cause false positives and false negatives. The invention provides a displacement sensor and a measurement method, in particular to a large deformation displacement sensor, which is suitable for slope slippage and structural deformation monitoring, especially suitable for high-precision continuous tracking measurement of small deformation and large deformation, and solves the problem of large structural deformation high-precision continuous monitoring problems. In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments desc...

Abstract

The invention discloses a large-deformation displacement sensor and a measuring method. The large-deformation displacement sensor comprises a housing; a displacement steering assembly which can rotateand translate and is arranged on the housing; a measuring rope which is arranged on the displacement steering assembly; a sliding assembly which is arranged on the housing and is connected with the displacement steering assembly; a plurality of deformation beams which are arranged on the housing; a plurality of springs, wherein one end of each spring is connected with the sliding assembly, and the other end of each spring is connected with the deformation beam; and a plurality of detection elements which are arranged on the deformation beam. According to the invention, high-precision continuous tracking monitoring of large structural deformation can be realized.

Description

technical field [0001] The invention relates to the technical field of structural health monitoring, in particular to a large deformation displacement sensor, which is suitable for slope slippage and structural deformation monitoring, especially for high-precision continuous measurement of small deformation and large deformation. Background technique [0002] Deformation and displacement monitoring is an important part of structural safety monitoring and evaluation, and is of great significance to ensure the safe service of engineering structures. [0003] As my country's transportation infrastructure construction gradually expands to the west, more and more cutting slopes will appear. Due to the complex geological environment around the transportation infrastructure in mountainous areas, geological disasters such as landslides and mudslides occur from time to time, which have become the main hidden dangers affecting the safe operation of the line. Among them, the deformati...
