The rapid development of infrastructure construction along the coastal areas of China has stimulated the development of major engineering projects, including high-speed railways, highways, airports, and nuclear power stations, all situated on soft clay terrain [7]. Consequently, the modification of soft clay has emerged as a pressing and crucial concern in geotechnical engineering. Presently, the widely adopted method for treating weak or problematic soils involves chemical curing, employing agents such as cement, lime, and other gelling agents. Utilizing cement as the curing agent, a profound mixture of soft clay and the curing agent can be achieved through techniques like grouting, anchoring, and mixed piling, among others [8]. In the context of pile foundations, this process transforms the soft clay into a robust pile characterized by integrity, water stability, and impressive bearing strength, facilitated by a series of physical and chemical reactions. Cemental soils significantly enhance the compressive strength of soft clay, mitigating the risk of excessive foundation settlement [9]. However, relying solely on traditional Portland cement as the curing agent to achieve a mixing pile that meets load bearing requirements presents practical challenges. Environmental factors and external loads can contribute to strength deterioration, cracking, and deformation in cement mixing piles, thereby posing risks to construction projects [10]. Therefore, there is an urgent imperative to develop high-performance stabilized soft clay capable of ensuring the stability of slopes and foundations [11; 12]. The mechanical properties of soft clay yield significant influence on the load bearing capacity of cement mixing piles in geotechnical engineering. Critical elements such as the dosages of the gelling agent, material components, and admixtures all contribute substantially to its curing effectiveness [13; 14; 15]. Recent research endeavors have honed in on augmenting the strength of stabilized soil by incorporating various types and quantities of natural and artificial fibers [16; 17]. With advancements in solid waste recycling, experiments have been undertaken to enhance the applicability of glass waste [18]. In practical applications, the incorporation of glass fibers in cement-based materials has exhibited promising outcomes. [PERSON] et al. [19] delved into the influence of glass fibers on the mechanical behavior and microscopic morphology of filling slurry, highlighting the pronounced influence of fiber content on compressive and flexure strength. Via performing pullout tests and shear tests, [PERSON] et al. [20] observed a significant improvement in the tensile strength of soft soil reinforced by glass fibers. [PERSON] et al. [21] introduced high-titanium glass fibers into stabilized soft clay, revealing marked variations in fluidity, compressive strength, elastic modulus, and other physical parameters based on the fiber content. [PERSON] et al. [22] conducted mechanical experiments to scrutinize the reinforcement rules of glass fibers in elemental materials, delving into the reinforcement mechanism through microscopy. Collectively, soil reinforcement with glass fibers efficaciously elevates the bonding degree of stabilized soft clay, enhances mortar's interfacial adhesion, inhibits crack expansion, and maximizes the improvement in load bearing capacity [23]. However, the factors governing the strength of cemental soft clay with fiber reinforcement have not been comprehensively examined, underscoring the need to enrich the research in this regard. In this study, uniaxial compression tests were conducted on fiber-reinforced cement-stabilized soft clay (FCSSC) to examine the changing patterns in its mechanical properties under different curing ages, lengths, and amounts of glass fibers. Microscopic image analysis was employed to unveil the glass fiber mechanism and identify the optimal content. Furthermore, we have established a damage constitutive model for specimens of FCSSC, verifying its accuracy and validity.
