| Abstract: | New advances in techniques and analytic methods of deepwater geotechnical investigation in recent years are introduced briefly.Drilling mode and sampling equipment in drilling and sampling techniques are diversified and effectively assembled in order to obtain good quality samples in different water depth and soil conditions.Piezo-cone penetration test was developed in the measurement method,design of porepressure unit,mini-size and multi-type of cone,in-time transmitting of data and the method of analysis.The concept and application of "SHANSEP" were proposed as a new laboratory test method which can minimize the sampling disturbance and more correctly estimate the undrained shear strength of clay. |
