The frost heave horizontal displacement is measured on the same position of two walls at the same place and different time. The central lake bank of the sculpture park in 2008 is still of a cantilever high retaining wall structure, and then (after 8 years), the frost heaving and horizontal displacement of different observation points of the retaining wall is measured to be large, the mean value reaches 33mm (see table 1), the allowable deformation capacity of the wall is exceeded, and frost heaving and horizontal displacement frost damage such as inclination, cracks, local collapse and the like is generated. The cantilever high retaining wall of the central lake bank of the sculpture park is completely reconstructed into the embedded type retaining wall structure in 2011, and frost heaving level displacement measurement of the embedded type retaining wall in the same section as the old address of the original cantilever high retaining wall in 2014, 2017 and 2021 by the invention groups shows that: the frost heaving horizontal displacement of the embedded type retaining wall is very small, the average value is only 2.33 mm-2.83 mm (see table 1), and the deformation of the wall is allowed. The embedded type retaining wall is tested to be complete in entity without freezing damage such as inclination, crack or collapse. The frost heaving horizontal displacement measurement test is completed by a rigid ruler precision distance measurement method.
