1) 截面补强法：在局部或沿构件全长以钢材补强，连成整体使之共同受力；

Reinforced method of section 1: in the local or along the full length of the component to steel reinforcement, and even as a whole to make common;

2) 改变计算简图：增设附加支承，调整荷载分布情况，降低内力水平，对超静定结构支座进行强迫位移，降低应力峰值；

2) change calculation diagram: added support, adjustment of load distribution, reduce the force level, to a statically indeterminate structure bearing forced displacement, reducing the peak stress;

3) 预应力拉索法：利用高强拉索加固结构薄弱环节或提高结构整体承载力、刚度和稳度。

3) prestressed cable method: the use of high-strength cables to strengthen the weak link of the structure or improve the overall carrying capacity, stiffness and stability of the structure.
