Abstract: In order to improve the bearing capacity of cement soil mixing pile, a new type of basalt fiber reinforced cement soil mixing pile is proposed. This work is mainly composed of three parts. Firstly, the construction process is proposed, which can make basalt fiber mix evenly in cement soil. Secondly, through the unconfined compressive strength test, splitting tensile strength test and triaxial shear test under different conditions, the optimal ratio of composite materials and the mechanical properties of pile materials are determined. Thirdly, the reliability of construction technology, optimal ratio and mechanical properties are verified by field testing the mechanical properties of borehole core samples.
