FIELD: construction.
SUBSTANCE: marine foundation (2) and method of slab lowering (28) are proposed against vertical rocking of a floating marine foundation (2). The marine foundation (2) comprises a floating structure (4, 6), a truss assembly (7) connected to the floating structure, and a thick (28) against vertical rocking, connected to the truss assembly. The floating structure includes a pontoon (6), located at least partially above water surface, where the marine foundation (2) is located; and at least three vertically arranged columns (4), connected with the pontoon (6) and having a large cross size compared to the pontoon connected to the column, which provides for partial displacement of the pontoon. The truss assembly (7) includes at least three separated walls (8), movably connected to the columns (4). Each wall (8) of the truss comprises at least two vertically arranged legs (10); the first leg (10) of the first wall (8), movably connected to any column (4), does not depend on the first leg (10) of the second wall (8) of the same column (4); and a cross-like fixture between at least two vertically arranged legs (10) of each truss wall (8). In the method of slab (28) lowering against vertical rocking of the floating marine foundation (2) they lower each wall (8) of the truss, forwarding at least two vertically arranged legs (10) of the wall (8) of the truss at the section of pontoon displacement, and they maintain at least two vertically arranged legs (10) of the truss wall (8) from the pontoon (6) in the lowered position regardless of legs (10) of the adjacent truss wall (8).
EFFECT: invention provides for stability and structural integrity of a structure.
