Problems solved by technology

[0004] 1. Plastic tensile grids are easily affected by the physical and chemical properties of plastic raw materials, resulting in reduced strength, high elongation at break ≥ 10%; poor creep resistance, poor thermal stability, and easy to cause engineering cracks and fractures , resulting in project failure and loss
[0005] 2. The reinforcing material used for steel-plastic composite geogrid is carbon spring steel wire (GB4357-89). Although it has high strength, it is easily corroded by harsh environments such as acid, alkali, and salt, especially for deep sea operations and embankment reinforcement. Due to long-term seawater erosion, the strength is low, the corrosion resistance is poor, and the service life is shortened. Therefore, it cannot fully meet the needs of permanent engineering construction
[0007] To sum up, with the country's strong support for the new material industry, the research and development of new functional materials, advanced structural materials and composite materials is imminent. The sudden collapse and cracking accidents of the road surface have caused serious threats to human traffic safety. Frequent personal injury accidents have caused huge losses to national property

Abstract

The invention discloses a highly smart LDTG composite geotechnical material and an engineering monitoring system thereof. The material and the system are characterized in that the composite geotechnical material comprises interlaced fiber bundles of a basis material, and at least one optical fiber is attached onto or to the inside of or to the surface layer of the fiber bundles along the extending direction of the fiber bundles which interlace in at least two different directions to form the biaxial or multiaxial composite geotechnical material. During engineering monitoring, a grating scanner is connected with the optical fiber in the composite geotechnical material, a computer with a data analyzing program and software is connected with the grating scanner, a caution curve of a collapse part is obtained after the processing of the data analyzing program and software of the computer, therefore processing and repair can be performed timely, and accidents are avoided.

Description

technical field [0001] The invention relates to a geotechnical material, which is mainly used as a reinforcement or reinforcement material in geotechnical engineering, and can realize the detection of stress environment changes in the soil, and predict the reliability performance of the engineering quality in advance, specifically a highly intelligent LDTG Composite geotechnical material and its engineering monitoring system. Background technique [0002] At present, there are many kinds of soil reinforcement or reinforcement materials (collectively referred to as geosynthetics) used in geotechnical engineering construction in China, and their performance characteristics and adaptability to the environment are different. Such as: uniaxially stretched plastic geogrid, multi-directional stretched plastic geogrid, three-way stretched plastic geogrid, multi-directional stretched plastic geogrid, steel-plastic composite geogrid, glass fiber warp grid Grid, polyester fiber warp-k...
