    • Abstract
  • In recent years, many piled mountains are built, and their characteristics are as follows: the loads are applied stage by stage, the construction period is long, and the total load is huge. Ground bearing capacity frequently cannot be satisfied by conducting common ground treatments. The time interval between applied loads stage by stage is usually long, in which consolidation occurs and the effective stress increases, resulting in the increase of strength and ground bearing capacity. Utilizing the increase of bearing capacity caused by the increase of soil strength is the key factor for the success of piled mountains. The increase of soil strength caused by consolidation is analyzed by using the effective consolidation stress method and shearing tests. A ground bearing capacity analysis method considering the increase of soil strength is proposed. A piled mountain case is analyzed by this method, and some suggestions are offered for similar projects.
