Interaction between Laterally Loaded Pile and Surrounding Soil

Abstract: A fully instrumented experiment was conducted to investigate the soil-structure interaction of single short, stiff laterally loaded piles. A hollow steel pipe pile with a diameter of 102 mm, a thickness of 6.4 mm, and a length of 1.524 m was installed in well-graded sand and subjected to increasing lateral load. The pile and surrounding soil were fully instrumented using advanced sensors, including flexible shape acceleration arrays, thin tactile pressure sheets, and in-soil null pressure sensors. The sensors attached to the pile were used to develop the compressive soil-pile interaction pressures and the lateral displacement along the pile length. The tactile pressure sheet sensors provided the soil-pile interaction compressive pressures on the circumference of the pile at a specific depth and along the length of the pile. The measured soil-pile interaction compressive pressures combined with the measured lateral displacement along the pile length were used to develop the soil-pile interaction fo...

Zero Extension Line Theory of Earth Pressure

Abstract: A theory of earth pressure for sand is developed. The theory is based on a simplified zero extension line field. Equations and charts for computing earth pressure coefficients with various values of wall roughnesses are presented. The results compare favorably with Sokolovski's coefficients of earth pressure. It is also shown that for active case in dense sand the direction of major compressive stress near the wall is almost vertical even for a very rough wall. A useful coefficient of roughness for the wall is defined. The results are compared with those predicted by Sokolovski, Coulomb, and Rankine theories.

A Coulomb-type solution for active earth thrust with seepage

Abstract: A Coulomb-type general solution for active earth pressure on the vertical face of a retaining wall with a drainage system along the soil–structure interface is presented. The soil is cohesionless and fully saturated to the ground horizontal surface. This condition may happen during heavy rainfall and is the most critical, when the active pressure reaches its peak value. In order to solve the problem, a theoretical, closed-form solution for the water seepage through the soil is first developed. This is used in a Coulomb-type formulation, which supposes a plane failure surface inside the backfill when the wall movement is enough to put the soil mass in the active state. The formulation provides Coulomb-like coefficients of active pressure, which solve the problem in a generic way. Comparison with published results obtained by hand calculation shows very good agreement.
