چکیده
Abstract The system of seabed Cone Penetration Test (CPT) is a kind equipment for offshore investigations. Seabed CPT used to assess multiple physical properties marine sediments. Constant-rate penetration mechanism the core part CPT, which adopts dual-cylinder drive penetrate probe rod into seafloor sediments at constant speed (2cm/s). At present, domestic and its almost all rely on imports. In process design, we found that traditional PID control hydraulic cylinder position accuracy low, so need study higher precision tracking method achieve uniform rod. this paper, Linear Time-Varying Model Predictive Controller (LTV-MPC) introduced, can two cylinders sediment with smaller rate error under condition changing resistance.

A Method for Predicting Pile Capacity Using Cone Penetration Test Data
The massive construction in poor lands has encouraged engineers to use deep foundations in order to transfer superstructure loads to the subsoil. Since soil excavation, sampling, and laboratory testing as a part of site investigation are relatively difficult, in-situ tests such as cone penetration test (CPT) as a very informative test may be recommended. The CPT has been widely used in engineer...

Dynamic cone penetration (DCP) test is used more in pavement design and construction, and less for subsurface geotechnical investigation and clay core dam. In the present article, evaluating geotechnical parameters of Sanandaj’s clay in the western region of Iran using the DCP test was taken into account. Accordingly, 6 trial pits with maximum depths of 15 m were excavated manually in various s...
