How to calculate the elevation of pile bottom

The calculation formula is: pile bottom elevation = measured hole depth+ground elevation.

When calculating the elevation of pile bottom, the following points should be paid attention to:

1. Ensure the accuracy and precision of the measured hole depth and ground elevation, and avoid inaccurate calculation results due to errors.

2. Considering the geological conditions and groundwater level of the construction site, the reasonable pile length and pile bottom elevation are determined.

3. According to the design and construction requirements of pile foundation, determine whether it is necessary to consider over-irrigation and filling coefficient.
