Embodiment

[0030] Optical fiber measurement technology has developed rapidly and is relatively mature. It has the advantages of small size, convenient installation, good durability, stable transmission signal, high sensitivity, and real-time monitoring. It has been widely used in many fields. Fiber Bragg grating sensor sensor not only has the characteristics of fiber optic sensor, but also can realize real-time monitoring of internal multi-point strain. It is the testing technology with the most development potential and application value in fiber optic sensing technology. The principle of fiber grating sensor monitoring is that the optical parameters of the optical fiber will also change when the structure under test is deformed. Call out its deformation index to reflect the deformation state of the measured structure. Through industrial professional processing technology, the ordinary ribbed belt and the fiber grating sensor are coupled together to form an intelligent ribbed belt (such...

Abstract

The invention provides an intelligent monitoring method for a potential fracture area of a reinforced soil retaining wall. The intelligent monitoring method comprises the steps that information geogrids are laid in a reinforced soil retaining wall in a to-be-monitored area in a layered mode; a digital three-dimensional model of the reinforced soil retaining wall in the to-be-monitored area is established; the strain position of an intelligent reinforced belt and corresponding strain mechanical data are acquired in real time, and the information is imported into the digital three-dimensional model; and the corresponding strain position information meeting the strain threshold value is extracted, all the strain positions meeting the strain threshold value are sequentially connected into a curve, and the area where the curve is located is the potential fracture area. The invention provides the brand new intelligent method for monitoring the potential fracture area of the reinforced soil retaining wall, the potential fracture area can be quickly and accurately monitored, early judgment and early warning are realized before a slope body is damaged, greater loss is avoided, the judgment difficulty of the potential fracture area is greatly reduced, and the discrimination efficiency of the potential fracture area is improved.

Description

technical field [0001] The invention belongs to the technical field of retaining wall monitoring, in particular to an intelligent monitoring method for a potential rupture area of ​​a reinforced earth retaining wall. Background technique [0002] As an anisotropic composite, the reinforced soil retaining wall has complex internal stress distribution and failure mode, and it is difficult to accurately grasp its force law. At present, there is no physical model of the constitutive relation of reinforced soil that can comprehensively describe the engineering properties, soil pressure distribution and force conditions that are in line with the actual situation in various situations. The shape of the potential rupture area of ​​the reinforced soil retaining wall is an important basis for the design of the length of the reinforced strip, but the determination of the shape of the potential rupture area is currently controversial, which will lead to a relatively conservative design ...
