The invention relates to an offset steel stand column for a railway sound barrier and belongs to the technical field of vibration and noise abatement in the field of environmental protection. The offset steel stand column comprises H-shaped steel, a stiffened plate, a steel base plate, an embedded bolt, a lifting hole, a grounding hole, a U-shaped bolt, a column top pressing plate, a mounting hole, a column top inside circular bead and a pressing plate hole, wherein the H-shaped steel, the steel base plate and the stiffened plate are formed in the form of welding; the H-shaped steel is connected with the column top pressing plate through the lifting hole, the pressing plate hole and the U-shaped bolt; the steel base plate is connected with a foundation through the mounting hole and the embedded bolt. The H-shaped steel of the offset steel stand column for the railway sound barrier provided by the invention is outward moved, the bolt and the nut are located at inside visible positions, the check and maintenance operations are both performed on the inner side of the road and no operation dead angle exists, so that the safe running of the sound barrier can be guaranteed; due to the design of the stiffened plate, the stress concentration of the welded cross section can be greatly reduced and the system safety can be increased; the offset steel stand column can be generally used for the present or upgraded sound barrier unit plate, the height of the unit plate need not be adjusted and the offset steel stand column can overall adapt to the mounting of the expansion joints on the bridges.
