EVALUATING STABILITY OF FOUNDATION AROUND WATER DROP WORKS WITH A HYDRAULIC-GEOTECHNICAL COMBINED METHOD

Abstract

 The stability of river-bed structures near water drop works, is affected not only by the river flow forces but also seepage flows and seepage pressures, especially sucking out of fine soil grain due to seepage pressures diminishes foundation strength. In this study, we developed hydraulic and geotechnical modelling to evaluate stability of foundation around water drop works. Numerical modelling and Laboratory experiment facility were set up for the studies. It is shown that the stability can be evaluated with fluid force acted on the body, and/or seepage failure of ground.
