Engineering Applicability Analysis of Basalt Fiber Modified the Red Clay in East China
High liquid limit red clay is widely distributed in East China,which can easily lead to engineering disasters if improperly treated.The feasibility of enhancing high-liquid limit red clay with basalt fiber was analyzed through laboratory geotechnical tests and numerical simulation.The laboratory test results were combined with the finite element difference software FLAC3D to simulate the plastic zone,stress,and settlement of two types of subgrade——the homogeneous red clay subgrade and the basalt fiber red clay subgrade under uniform load conditions.The aim was to compare the performance of the two types of subgrade.Laboratory geotechnical test results indicate that adding basalt fiber can significantly improve the cohesiveness,unconfined compressive strength,and static elastic modulus of red clay.The numerical simulation demonstrates that fiber reinforcement technology can improve soil plasticity,anti-squeezing ability,and alleviate settlement deformation.The reinforcement of high-liquid limit red clay with fiber technology provides a new theoretical basis for improving special soil roadbeds.
