1. Effective pile length refers to the actual pile length after construction.
For example, the design pile length of a project pile foundation is 27 meters, so there is bound to be deviation in actual construction. If it is found that 27 meters is too long (or too short) after construction, it is necessary to add 5~ 10cm to the foundation elevation, and then remove the redundant part (or weld the extension). This is the effective pile length, that is, 27 meters minus the cut-off part (or 27 meters plus the welded part).
2. If the effective pile length is not equal to the design pile length, most of them are end-bearing piles, and a few friction piles encounter hard layers or boulders. The general effective pile length of friction pile is the design pile length.
