| Abstract: | Taking construction of an arch thrust pier base as an example,the article discussed a construction plan for deep excavation bridge base in composite supporting mode as "row pile + top beam + internal bracing"sand using finite element value model.it calculated the stress and excavation stability for such a structure.lt is proved that this composite supporting mode is valid and feasible. |
