| Abstract: | In view of the cracks emerging from simply supported beam u-shaped gravity type abutment in a mountainous territory of chongqing,an examination and analysis are made to obtain the crack mechanism.The solution is to consolidate the groundwork by grouting,and strengthen abutment by prestressing force,self-advancing anchor and steal reinforced concrete vertical beam.The method achieve good results. |
