Title:
CONSTRUCTION OF HYBRID TSUNAMI EMBANKMENT
Document Type and Number:
Japanese Patent JP2016211312
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a simple and low-priced tide embankment facility with resilience and a flood protection function, in view of a fact about numerous tide embankments destroyed in a huge tsunami at the time of Great East Japan Earthquake, during which a tsunami that overflew a tide embankment scoured a foundation ground of a rear slope surface on a downstream side and absorbed concrete lining on the rear slope surface on the downstream side, leading to erosion of the embankment and loss of an entire cross section, as well as total loss of functions as a tsunami protection facility, consequently resulting in aggravation of tsunami damages and loss of many lives, properties and infrastructures.SOLUTION: As means to solve the problem, an upright wall-type tide embankment (a hybrid tide embankment of a structure combining different types of construction materials) having a top edge height higher than a flood level accompanying a forecasted tsunami wave height is constructed behind an existing tide embankment, to withstand wave force of a tsunami wave height (about 5 m to 10 m) at a time of a magnitude 8-class earthquake.SELECTED DRAWING: Figure 11
