| Abstract: | With the construction of coastal highway,the problem of soil subgrade strengthening is more and more serious.According to the engineering properties of soft soil subgrade and fly ash concrete pile composite,this paper summed up the soft soil area of concrete pile composite foundation bearing capacity and settlement calculations,and proposed a design approach of making the deformity coordinated by the transition section of the bridge abutment and the general overlap of soft soil subgrade. |
