Abstract:
Knowledge of the correlation between soil property indexes for the same geological unit soil can solve the small sample problems in practical projects. Based on the collected data of physical and mechanical property indexes of marine silt in the reclamation land projects in Shenzhen, correlation of physical properties indexes, mechanical properties indexes of dredged fill linear regression method was used to analyze the correlation between each physical and mechanical property index of dredged silt and undisturbed silt, and to establish the corresponding regression equations. The results showed that other soil property indexes of dredged silt can be estimated accurately using the empirical regression equation based on two known parameter indexes, including one of liquid limit or plastic limit and one of other soil property index. Mechanical property indexes of dredged silt can be estimated accurately using the empirical regression equations between physical property and mechanical property indexes of undisturbed silt. The results have important application values for the reasonable selection of soil property indexes in the treatment engineering of marine silt foundation.
