A quasi-static model test series using model pile and soil are performed to measure stresses and strains in the soil around the pile. A model pile is buried 250mm in the ground and loaded at the pile top. The stresses and strains in the ground are measured by pressure transducers and coil type displacement gauges. According to the test results, the following findings are obtained. In the soil around the pile tip, the resultant stress of normal stresses is act in a radial direction from a point 2.5〜3.0D(D: diameter) below the pile tip. Stress strain curve in quasi-static test is matched with that of static test.
