Disclosed are a complex diaphragm wall for environmental protection of a landfill in a soft soil area, and a construction method therefor. The complex diaphragm wall comprises a flexible core wall arranged surrounding a landfill, wherein the depth of the flexible core wall is sufficient for the flexible core wall to extend from the earth's surface to be embedded in an impermeable layer; plastic wall bodies are respectively arranged on inner and outer sides of the flexible core wall; a support wall body is respectively arranged on an inner side of the internal plastic wall body and on an outer side of the external plastic wall body; a transition area is arranged between the internal support wall and the landfill; and an underground water pump-drainage well is arranged in the transition area. The present invention, according to certain procedures, i.e. constructing the support walls, vertically grooving, vertically installing the flexible core wall, preparing plastic concrete based on specific proportions and constructing the plastic wall bodies in an underwater pouring manner, and by means of the technical solution, can effectively isolate a hazardous waste landfill from accidental liquid leakage to protect soil and underwater on the premise of ensuring the stability of a surrounding embankment and a foundation of the landfill.
