The utility model provides a micro-friction load force transmission plate used in a geotechnical engineering triaxial compression test, which includes a round bearing plate, wherein a sliding block stop bar is arranged at the center of the round bearing plate; six first rectangular grooves are radially and evenly distributed in the peripheral direction of the round bearing plate; a first rectangular groove is formed between every two adjacent first rectangular grooves; a second rectangular groove is formed between every first rectangular groove and every adjacent third rectangular groove; the first rectangular grooves, the second rectangular grooves and the third rectangular grooves are inserted into first guide rails, second guide rails and third guide rails correspondingly and respectively; two arc grooves are formed in each guide rail; steel balls are arranged in the arc grooves; a plurality of circles of sliding blocks are arranged on the guide rails in the radial direction of the round bearing plate; the sliding blocks can slide freely on the guide rails in the radial direction through the steel balls. According to the utility model, an axial load is applied to the sample through the plurality of circles of automatic sliding blocks, and the frictional resistance between the sliding blocks and the round bearing plate is reduced through the steel balls at the same time, so that the end restraint problem of the sample can be welled solved.
