Conductive polymer-based soil deformation monitoring system and method

Abstract

The invention discloses a conductive polymer-based soil deformation monitoring system and a conductive polymer-based soil deformation monitoring method. The system comprises a soil body on which conductive polymer is laid, wherein the soil body on which the conductive polymer is laid is connected with a wireless data acquisition instrument through a wire; the wireless data acquisition instrument is connected with a network through a GPRS (General Packet Radio Service) module; the network is connected with a database through a network interface; the network is connected with the database and a server; the conductive polymer-based soil deformation monitoring system is integrated in an intelligent traffic system as required; smart conductive polymer has good durability and low cost; a sensor is not required to be embedded in a material according to a self-detection technology, so that the phenomena such as reduction in strength and performance of the material caused by implantation of an external sensor are avoided; the detection is accurate and timely and the performance is stable; a soil body fracture plane can be positioned by extracting reinforcing material deformation, stress characteristic information and the like; and a theoretical basis is provided for reinforcing and repairing the soil bodies such as a roadbed.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a soil deformation monitoring system and method based on conductive polymers. Background technique [0002] In recent years, geotechnical materials (such as geogrids, etc.) synthesized by polymers have been widely used in geotechnical engineering such as embankments, slopes and retaining walls because of their high strength, corrosion resistance, flexibility, and convenient transportation. Reinforcement works. However, the research on reinforcement-soil interaction mechanism and calculation and analysis methods lags behind the development of engineering practice, which shows that the calculation results according to some existing methods cannot reflect the significant effect of geosynthetics on improving the stability of structures.

However, the research on the mechanism of reinforcement-soil interaction and calculation and analysis methods lags behind the development of engineering practice, which shows that the calculation results according to some existing methods cannot reflect the significant role of geosynthetics in improving the stability of structures

This shows that the reinforcement mechanism of geosynthetics and the possible failure mode of the reinforced soil have not been clarified, which makes the calculation method lack pertinence. In this way, the reinforcement application of geosynthetics has a certain blindness and is not May seriously affect its promotion and technological development

In addition, in order to understand the stability of reinforced soil engineering in the whole life cycle, external stability indicators such as settlement and horizontal displacement of some discrete points of reinforced soil are generally monitored, but practice shows that only the internal damage state of reinforced soil develops to To a certain extent, there will be obvious changes in settlement, etc., which often delays the best reinforcement time

In view of the above reasons, people began to strengthen the field test and research on the internal stability index of reinforced soil, but the current test methods are still far from perfect
