一、前言随着国民经济的发展和沿海城市的开放,加快港口建设已成为当务之急。由于原有陆域不敷应用,故必须大力扩充,采取四周筑堤、中间吹填浮泥的方法,是目前常用的比较经济有效的围海造陆方法,由于这些浮泥经过铰吸吹填,故含水量极高,一般为100～200％,最高可达到300％以上,同时结构被破坏,故强度基本上为零,这样的地基,我们称为超软地 I. Introduction With the development of the national economy and the opening of coastal cities, speeding up port construction has become a top priority. Since the original land area is not enough for application, it must be vigorously expanded. Taking the method of embankment built around and floating mud filled in the middle, it is the most economical and effective method of land reclamation at present. Because these floating muds are blown through hinged suction, So the water content is extremely high, generally 100-200%, up to 300% or more, while the structure is destroyed, so the intensity is basically zero, so the foundation, we call super soft ground
