Summary: This paper analyses the stress-strain behavior of fiber-reinforced sand using drained triaxial compression tests. The behavior of fiber-reinforced sand is described using the stress-plastic dilatancy equation of the Frictional State Concept for different shear phases. The characteristic shear phases can only be determined using the eta-D-p relationships, which are rarely shown in the literature. Tensile strains are shown to be necessary for achieving the strengthening effect of fiber reinforcement, and the stiffness of the fiber-sand composite decreases in the absence of tensile strains below a certain threshold value.

Summary: The study indicates that using a partial reinforcement method with short discrete synthetic fibers can significantly improve the cohesion and shear strength of sand, prevent static liquefaction, and enhance the suction of unsaturated sand. The failure mode and extent of slope damage depend on the fiber content.

Summary: Adding discrete fibres to sand has been shown to improve sand's strength and liquefaction resistance. The anisotropic distribution of fibre orientations introduces anisotropy in the liquefaction resistance of reinforced sand. Fibre reinforcement densifies the sand and provides confining effects, improving its liquefaction resistance. The strength envelope of fibre-reinforced sand under triaxial compression is influenced by fibre content, while the strength envelope is not affected by fibres under triaxial extension. The stress contribution of fibres under undrained loading causes the stress ratio initiating the excess pore water pressure (ESP) reversal to change, depending on the fibre content and density state under compression.

Summary: A unified critical state model has been developed for both clean sand and silty sand using the modified Cam-clay model. The model features a new critical state line equation in the e-ln(p) plane that can handle both straight and curved test results, eliminating errors in calculating plastic volumetric strain. The model also considers the transformed stress tensor based on the SMP criterion for proper shear yield and failure of soil under three-dimensional stresses, and incorporates the intergranular void ratio with fines influence factor for silty sand.

Summary: In recent years, the use of natural fibres and biopolymers in many products has gained acceptance due to the serious reduction in petroleum resources and concerns about synthetic plastics. Lignocellulosic fibre polymer biocomposites, particularly those made from oil palm fibres (OPFs), have attracted attention for their wide availability, low carbon emission, and biodegradability. However, the mechanical properties of OPF biocomposites and the factors influencing their performance have not been thoroughly examined.

Summary: Microbially induced calcium carbonate precipitation (MICP) technique is an eco-friendly method for soil improvement, which enhances soil strength through cementation of sand particles. It has the potential to create stable bio-stabilized soil columns and produces homogeneous bio-cemented soil samples. In addition, there is no significant difference in the amount of calcium carbonate precipitation between sand and silty sand.

Summary: This study introduces two effective and sustainable materials, microbial biopolymer (MB) and palm fibers (PF), for cracking and erosion control in sand-clay mixtures. The results showed that MB could significantly improve the resistance of the soil to cracking and scouring, and the improvement increased with increasing MB content. Additionally, PF positively affected the anti-crack and antierosion properties of the soil.

Summary: Adding tension-resistant fibers to cohesionless soils can effectively strengthen the soils and increase their liquefaction resistance. Shaking table tests showed that fiber reinforcement can slightly delay and reduce excess pore pressure accumulation, as well as attenuate the degradation of acceleration amplitudes and stiffness. However, the benefits of this reinforcement technology may be minor when the fiber-reinforced soil is at shallow depths.

Summary: This study focuses on the surface settlements caused by twin tunneling in silty sand. A comprehensive field monitoring scheme was conducted to measure the surface settlements, and the influence of different shield operational parameters was explored. The study observed an inverted bimodal shape in the total settlement profiles, which provides important insights for underground space engineering.
