| Abstract: | This paper introduces grouting mechanism,geological condition for test,bottom grouting amount and its detection,and studies the bearing capacity of grouting pile under different grouting amount.It is indicatedthat bearing capacity is largely improved and settlement is largely reduced after grouting through test.The paper also puts forward problems for further research. |
