    Initial stresses of soil body are important upon penetration of long length underground pipelines (tunnels) into soil. If there is a free space between cassing (lining) and body the soil grains move to the free space. Value of free space is called “soil loss”. Movements may occur due to this free space filling with soil at the daylight surface. If the movements reach a great significance, aboveground structures and neighboring underground structures may be significantly damaged. Therefore, an evaluation of soil subsidence and pipeline (tunnel) stability are of great concern upon the pipelines (tunnels) designing.
