一、软土分带与类型我国的软土,按其成因与分布,拟划分为三个带: 1.内陆软土带包括湖相及河漫滩相; 2.近海软土带指海底软土; 3.沿海软土带指沿海城市及港口的软土。在上述的三个带中,内陆软土其实并不太软,其地基承载力往往可达到1.2公斤/厘米~2,有时甚至达到1.5公斤/厘米~2。海底的软土最松软,其孔隙比能达到3.0,含水量经常达到150%以上。沿海城市及港口的软土,居于上述两者之间,并可按成因与性质,再划分如下: (1)泻湖相沉积温州、宁波属于这种类型。在表层的褐黄色粘土之下,为厚度
First, soft soil zoning and types China’s soft soil, according to its causes and distribution, is to be divided into three zones: 1. Inland soft soil zone including lacustrine facies and floodplain facies; 2. Offshore soft soil zone refers to submarine soft soil 3. Coastal soft soil refers to soft soil in coastal cities and ports. In the above three belts, inland soft soil is not very soft, and its foundation bearing capacity can often reach 1.2 kg/cm2, sometimes even reaching 1.5 kg/cm2. The soft soil on the seabed is the softest and its porosity ratio can reach 3.0, and the water content often reaches more than 150%. The soft soils of coastal cities and ports are located between the above two, and can be further divided as follows according to their causes and nature: (1) Lagoon phase deposition Wenzhou and Ningbo belong to this type. Below the surface of the brownish yellow clay, the thickness is
