- Abstract:
- With the upgrading of pipe jacking equipment and the improvement of construction technology, the friction of long-distance grouting pipe jacking has been greatly reduced. The existing empirical formula can no longer accurately calculate the jacking force. This study collects a large amount of jacking force data from pipe jacking projects, and divides the jacking force growth into three stages to optimize the average friction value range. The upper and lower limits of the jacking force calculated through the optimized value range can cover 90% of the data, with average relative error of about 30%, which has a certain degree of accuracy and can serve as a reference for future pipe jacking force calculations.
