Micro-piles are widely used because of its own advantages, but relatively few theoretical studies about its anti-slide mechanism. Firstly, the mechanical properties of the model pile into calibration tests, to get of elasto- plastic session elastic modulus, were 0.69 x l04 MPa and 0.04 x 104 MPa. Through the different pile spacing under a single row of miniature pile reinforcement gravel soil landslide indoor model experiment to study the micro-piles a- gainst sliding mechanism. The test results show that： different pile spacing, single row of micro-pile soil pressure mainly concentrated in the range of slip surface more than 1/3 of the pile. The pile spacing is small, soil arching effect, the greater the micro pile skid failure critical moment, the micro pile can withstand landslide thrust the grea- ter skid th＇e better.
