The invention discloses a railway vehicle body structure and a through channel mounting hole machining method thereof. The vehicle body structure comprises an underframe edge beam (12) and an underframe end beam (13) obtained by machining the underframe edge beam. The first horizontal rib, the second horizontal rib, the third horizontal rib and the fourth horizontal rib are sequentially arranged from top to bottom, the outer side rib (12a), the middle vertical rib (12c) and the inner side rib (12d) are sequentially and vertically arranged between the first horizontal rib (12n) and the third horizontal rib (12g) from outside to inside, a first inclined rib (12b) is arranged between the outer side rib and the middle vertical rib, and the inner side rib is arranged on the second horizontal rib (12e) in an outwards inclined mode. The first inclined ribs intersect with the upper ends of the inner side ribs, so that at least three triangular cavities extending in the horizontal direction are formed between the firs
