| Abstract: | The basic theories and composition of the elastmeter are introduced, followed by the properties of the marine ooze. The application of GA-elastmeter produced by the French Menard Company to the in-situ measurement of the marine ooze are discussed carefully; then the results are analyzed; the moduli of pressuremeter, deformation and compressibility increase with the hole’s depth to the stabilization step by step; at the same time, preportional limit pressure、ultimate pressure and bearing capacity have the tendency to increase. It is proved that the result of this test can be used to the engineering design and the similar project for reference. |
