The invention relates to the technical field of cable intermediate head installation interface pressure measuring, in particular to a cable prefabricated type intermediate head interface pressure axial distribution measuring method. The method comprises the following steps that transverse sections of n positions in the axial direction of an intermediate head are selected as measuring sections; a plurality of positions on the same transverse section are selected as pressure measuring points; the pressure measuring points of the corresponding positions on the measuring transverse sections of then positions are arranged on the same axial line; pressure sensors are arranges at the pressure measuring points; and down-leads of the pressure measuring sensors are connected with a data collectingsystem to measure interface pressure at real time. According to the axial distribution situation of the prefabricated type intermediate head interface pressure, the pressure sensors are arranged at different interfaces, alignment of the down-leads is arranged, and therefore the multiple measuring points can meet the experimental aim and not disordered. Intermediate head interface pressure information can be reflected comprehensively, and important experimental support is provided for analyzing interface pressure distribution regulation and influence factors.
