| Abstract: | Jianning Zhifeng highway stone arch bridge presents itself abutment subsidence and part structural crack after many years of use. The application of grouting to consolidate foundation, combined with consolidating treatment of setting umbrella arch up and inverted arch down, has achieved good effect of engineering. Combined with engineering practice, carrying through the analysis of disease reasons and design of consolidating treatment project, and particular introducing of construction techniques and the main points of quality control, that can provide a reference for other similar projects. |
