Abstract： Referring to the special conditions as deep foundation hole of large bridge adjacent to high-voltage wire, existing railway line, rural residential area and workshops so on, new exploding technology with rock & earth compressing is raised, and integrated with water compressing exploding to proceed deep foundation hole construction, accelerating the working progress, especially preventing stones from flying freely, lessening exploding shock, and keeping safety, reducing the extent to disturb residents, good results are achieved.
Keywords： existing railway line; deep foundation hole construction; water-compressing explosion; earth-compressing explosion
