Construction method of bubble mixed light soil embankment

The invention discloses a construction method of a bubble mixed light soil embankment. The construction method comprises the following steps: excavating a to-be-constructed area to form a horizontal construction surface; filling, leveling and compacting a horizontal construction surface; the surface of the side, close to the slope bottom, of the horizontal construction face is excavated to form a step structure; compacting the surface of the step structure and constructing on the top surface of the step structure to form an embankment foundation; constructing on the embankment foundation to form a panel foundation; a prefabricated panel is installed on the panel foundation to form a pouring cavity; bubble mixed light soil is poured into the pouring cavity, and a bubble mixed light soil layer is formed; and paving on the horizontal construction surface and the top surface of the bubble mixed light soil layer to form a road surface to obtain the embankment. According to the method, the roadbed of the expressway
