| Abstract: | Taking the through bowstring arched bridge as an example,the article preliminarily discusses its lifting feasibility,and analyzes the necessary considerations and cautions when lifting in order to provide the benefit thinking for the future reconstruction of the similar bridges.The article carries out the space finite element analysis on various lifting conditions by using the finite element software to achieve the stress-error rule for providing the reliable basis for the construction. |
