Abstract: Introduce the L circle bridge of some separate cloverleaf junction 144.94m long six stretch continual ridges. The construction of the main structure of the bridge floor was finished.After some areas were re-filled with soil,some stake foundations were found to subside in varying degrees.Through the calculation and analysis of the stake foundations subsidence,the plan of single pipe and three pipes stake foundations pressure circle spray reinforcement was adopted,and the stake foundations were re

Key words: circle bridge, calculation analysis of the stake foundations, subsidence pressure circle spray reinforcement
