Abstract
Using the working mechanism of reinforced composite pile,and based on a practical engineering,some static load tests were carried on pipe piles and pipe pile-soil-cement composite piles,and some low strain tests were carried on pipe pile in different ages of soil-cement composite pile.The bearing capacity of pipe-soil-cement composite pile was greatly improved,and can meet the bearing capacity requirements of the project with a shorter pile length,and can greatly reduce the project costs.The low-strain test results reveal the coupling between pipe pile and soil-cement is obvious and the bonding strength increases gradually with the increase of age.关键词
