摘要

Transient pore pressure distributions may be estimated by regarding submerged soil as a three-phase medium (gas, water and solids). Thus new approaches to release pore water pressure have been developed in order to stabilise endangered slopes in low permeable soil. The applied concept of using reversely inclined bore holes to release pore pressure in the vicinity of potential shear zones is described. The proposed way of pore pressure release in order to increase safety of unstable slopes is widely applicable. Examples of applications to increase safety include cut slopes as well as river dikes. Additionally results of calculations and field measurements are provided and discussed.
