The invention relates to a method to test friction resistance at inner and outer sidewalls of pipe pile through in-situ test. The method comprises embedding a strain sensor at inner or outer sidewalls of pipe pile to measure strain variation generating on pipe pile body under the action of load; carrying out static load test with the soil plug remaining in the pipe pile to obtain the strain variation &#x3b5;of the pipe pile body at the isoil layer; taking out the soil plug remaining in the pipe pile and carrying out static load test to obtain the strain variation &#x3b5;of the pipe pile body at the isoil layer; and obtaining the friction respectively at the outer and inner sidewalls of the pipe pile at the isoil layer according to the measured strain variation, &#x3b5;and &#x3b5;.
