![]() During high speed tests on dry sand an excess of pore air pressure is observed. In the range of applied loading rates, theĪngle of internal friction of the sand increases up to 2 degrees (strength increases 5-10%). In dry sand, a higher loading rate gives higher shear strength. The characteristics of excess pore pressure in sand and in the sand near the pile toe during a quasi-static The effect of loading rate on the strength of sand and on the bearing resistance of a pile in sand ![]() The research pointed at answering two fundamental questions: The testing program consists of a series of triaxial tests for sandĪnd a series of load tests on a model pile embedded in sand in a large calibration chamber. A series of laboratory tests has been carried out. Statnamic) pile load tests, a research project has been started to investigate effects of the loading rate on the bearing capacity of a pile in sand. In order to improve the interpretation of the quasi-static (e.g.
