Abstract
The application of soil improvement techniques in geotechnical engineering plays a crucial role in enhancing foundation bearing capacity, reducing settlement, and optimizing construction conditions. Against the backdrop of practical engineering requirements, this study addresses the limitations of traditional improvement methods under complex geological conditions by proposing a novel soil improvement technique based on composite material reinforcement. Through an integrated approach combining laboratory experiments, numerical simulations, and field tests, the mechanical properties and long-term stability of the improved soil were systematically analyzed. The results indicate that this technique significantly increases the shear strength of the soil while decreasing its permeability coefficient, demonstrating superior performance particularly in soft ground foundation treatment. Furthermore, the innovative incorporation of environmentally friendly additives effectively mitigates the ecological impact of chemical materials. This research not only highlights the high engineering applicability of the proposed technique but also provides new insights for green geotechnical engineering, offering theoretical support and technical references for similar engineering practices.Key words:Soil Improvement Technology; Composite Material Enhancement; Shear Strength; Environmentally Friendly Additive; Soft Soil Foundation Treatment
