摘要
针对体外预应力加固梁时的受力机理,提出采用体外预应力加固设计的计算公式和应满足的条件,其在施工中简单易行,可供同类加固设计参考使用。
According to the theory of external prestressing strengthening bridge, the calculation formula and relevant conditions of external prestressing strengthening design is proposed. This method is easy to use in construction and can be a reference for strengthened design of other bridges.
