| Abstract: | Using lime and stone pile to improve of back abutment filling for Shangfengling bridge in contract No. B8-2 of Liwen expressway, the results of standard penetration test and the experience traffic about one and a half years show that contract No. B8-2 of Liwen expressway almost has no jump the beginning of bridge. Thus, the technology of back abutment filling of for bridge is very successful and has significant meanings for improving service function and using quantity. |
| Keywords: | bridge engineering lime and stone pile back abutment filling quality controlled stander |
