The invention provides a cascading-effect concrete landscape wall structure and a construction process thereof. The landscape wall structure is formed by pouring of multiple layers of concrete from bottom to top. An integrated structure is formed in each layer of concrete, outer edges are disconnected and not connected, fault space is formed, and ornaments are integrally poured to the fault space. According to the cascading-effect concrete landscape wall structure and the construction process thereof, by means of the specific process technology, the sensory effect expected by people is achieved, and therefore individuality themes, the ornamental effect, the streamline form and the environmental protection function are considered.
