“…Cui et al [5,111,112] investigated the piezoresistivity of conductive-polymer-doped geobelts, which serve not only as reinforcements but also as monitoring devices. The self-sensing geobelt was composed of CB-filled high-density polyethylene (HDPE) and was fabricated for both industrial and laboratory applications.…”

“…Longevity is another limitation: Geosynthetics are often used in infrastructure projects with long lifespans, such as roads, embankments, and retaining walls [5,6]. However, the electronic components integrated into smart geosynthetics may have shorter lifespans compared with the geosynthetic material itself.…”

Civil infrastructure monitoring with the aim of early damage detection and acquiring the data required for urban management not only prevents sudden infrastructure collapse and increases service life and sustainability but also facilitates the management of smart cities including smart transportation sectors. In this context, smart geosynthetics can act as vital arteries for extracting and transmitting information about the states of the strain, stress, damage, deformation, and temperature of the systems into which they are incorporated in addition to their traditional infrastructural roles. This paper reviews the wide range of technologies, manufacturing techniques and processes, materials, and methods that have been used to date to develop smart geosynthetics to provide rational arguments on the current trends and utilise the operational trends as a guide for predicting what can be focused on in future researches. The various multifunctional geosynthetic applications and future challenges, as well as operational solutions, are also discussed and propounded to pave the way for developing applicable smart geosynthetics. This critical review will provide insight into the development of new smart geosynthetics with the contribution to civil engineering and construction industries.

“…Geosynthetics offer the advantages of a small specific gravity, strong overall continuity, high tensile strength, and corrosion resistance [1]. To date, geosynthetics have been applied in various engineering fields, mainly in isolation, reinforcement, drainage, filtration, and protection [2], and their long-term deformation performance is crucial for structural safety and stability.…”

A new top-pressure creep test device was developed to simulate the stress conditions of geomembrane in a real working state. CBR puncture and top pressure creep tests under different load levels were conducted using this device to study the creep characteristics of the geomembrane at top pressure. The top pressure creep reduction coefficients under different load levels and design lives were calculated and compared with the regular tensile creep reduction coefficients. Quantitative relationships between the creep-reduction coefficient, design life, and failure strain were established to predict the top-pressure creep-reduction coefficient. The results indicated that the top pressure creep reduction coefficient was greater than that of regular tensile creep. The creep reduction coefficient changed minimally with an increase in the design life. The top pressure creep reduction coefficient remained stable with an increase in the top pressure area strain for different design lives. Based on the results, to improve the safety and durability of engineering structures, the top pressure creep reduction coefficient should be used in the design of geosynthetics affected by the top pressure.

“…Hot pyrocondensation pipes (HPPs) were used to protect the SEGB against the influence of water. The effects of thermal oxidation, ultraviolet radiation, acid-base corrosion, and cyclic loading on SEGB properties were then tested [32,33] However, the tensile strength of SEGB and the friction between SEGB and the soil after sealing were reduced, and the manufacturing difficulty was increased. The strain-conductivity response may be complex because the whole geobelt is conductive and contacts each other.…”

In recent years, there is a growing demand for materials that can both improve the mechanical properties of structures and carry out health monitoring and risk warning. In this case, in order to realize distributed deformation monitoring, a new method of making geogrid by 3D printing technology is proposed. The grille rib is made by embedding the conductive polymer (ground carbon fiber as conductive filler) into the insulating shell (PLA material) in the specified path, and then the rib is vertically crossed into each other to form a grille sample. In order to study the distributed deformation monitoring function of this grid, a manual push–pull testing machine was used to conduct a load–unload experiment to analyze the change rule of resistance on the grid plane. The following conclusions were obtained: the closer the ribs are to the load bearing point, the greater the change in resistance, and conversely, the farther the ribs are from the load bearing point, the smaller the change in resistance. Depending on the geogrid network characteristics, the electrical resistance distribution on the geogrid plane can be obtained by superimposing the resistance values of the horizontal and longitudinal ribs, then the location and the magnitude of deformation can be estimated. Additionally, this study carried out numerical simulation of the grid model based on ANSYS 15.0 software and compared with the loading experiment results to verify that the force deformation position can be retrieved through the change of resistance.
