Abstract Testing study is made on the bearing capacity of pipe piles socketed in softrock. On the basis of large amount of construction information of driven and redriven pipe piles with the bearing stratum of mudstone，the settlements of pile top and pile bottom under top vertical load are measured for piles subjected to axial loads. An improved formula is given to calculate the axial force of the pile at its bottom. The friction parameters of the soils around pile are calculated by back analyzing method on the basis of measured load-settlement information of static test．The testing study and analysis results indicate that the softrock such as mudstone layer should not be bearing stratum of pipe piles，before effective measures are adopted to eliminate the possible great settlement of buildings.
