As developing rapidly for China coast economy is increasing with offshore production activity, Storm Surge Disasters in recent years
Caused by lose be in obvious ascendant trend in general.According to statistics, the invasion and attack of only 2005 typhoons, cause China coast
At dyke damage 10,266, length is 600.7 kilometers, and economic loss reaches 329.8 hundred million yuan.As resisting off-lying sea wave stroke
Sea wall is to protect the important job facilities that coastal area exempts from tide, wave attacks, and the destruction of sea wall will cause serious consequence.Largely
Sea wall accident shows：More unrestrained is a major reason for causing sea wall to destroy, and destruction caused by it is mainly manifested in three aspects：
First, impact to levee crown and adverse grade and washing away；Second, sea wall is set to come down on the brush of drawing of adverse grade；Third, contain the sea wall soil body
Water increase causes sea wall unstability.But the influence degree of levee crown overtopping wave is mainly controlled by crest elevation of levee, when more than certain

And this more shape wave state, it is particularly important for analyzing influence of the more unrestrained water body to adverse grade pedestrian, vehicle and works etc..It is simultaneously special
Needed in the case of different, such as in engineering using when overtopping wave size is to design the intensity of rear bank protection produced by single big ripple, by
In more unrestrained result caused by continuous wave action can not be caught in time, can only finally be replaced using mean overtopping discharge,
This will bring certain risk to engineering design.When manually repeatedly being weighed to water body in addition, there is also water loss, and
The possibility misread；When particularly carrying out adding wind condition test in the sink, gauger in the sink can produce one to wind speed
Fixed obstruction and interference effect, these all will produce certain influence to result of the test.
