Fractal feature of pore size distribution of a marine soft soil and its application;

Experimental study on consolidation properties of two marine soft soils

When the expressway is built on marine silt and silt soil in the coastal areas,as this marine soft soil is of high compression settlement,slow drainage consolidation and poor foundation stability,many engineering problems are appeared during the construction period of high-grade highway even after the construction is completed.

Settlement features of embankment of Lianyungang marine clay;

Based on the test results of a large number of samples of marine soft soil ingathered in Lianyungang, the statistics and analysis about physical and mechanical indexes of marine clay are made, and the relationships between these indexes have been obtained by using linear regression analysis.

Based on statisticing physical and mechanical properties of Lianyungang marine clay,the stress and deformation of gravity retaining wall in marine clay has been analysised with two-dimensional finite element software.

Based on the statistical data of 120 works in Ningbo, geological origin, mechanical composition, mineralogical composition, soil indicators, micro-structure and structural feature of Ningbo marine soft clay were studied, and were compared with other coastal soft clays.

Experimental investigation on the compound foundation of highway composed by marine super-mollisol and CFG pile;

In Shenzhen area,there is much marine soft soil which is of low bearing,high compression and high natural water content.
