In the offshore areas of Dalian, China, a coastal reclamation project is ongoing for building an international airport. In the project, the possible excess settlement due to consolidation and creep of soil is one of the main concerns. In this paper, three series laboratory tests, i.e., conventional consolidation and rebounding tests, one-dimensional creep tests and triaxial creep tests were carried out to study the compression behaviors of the marine clay. All these tests were performed on undisturbed samples procured from the depth of 10 and 18 m below the seabed of Jinzhou Bay seabed. The compression and swelling indexes obtained from the conventional compression and rebounding tests show that marine clay presents much higher compressibility and special attention should be paid to the settlements in the project construction. The results of both one-dimensional and triaxial creep tests show that the creep deformation of soils increases with elapsed time and stress level. In addition, failure of soil hardly occurs in the process of creep and the soil deformation could eventually stabilize at any given stress level even in triaxial tests. At last, the stress-strain-time relationships were simulated to estimate the time-dependent behaviors of the marine clay.
