The analytical results show that, as the transverse rigidity decreases, the area of compressive region increases and the longitudinal effectiverigidity ratio decreases.
结果表明，随横向刚度减小，截面受压区面积增大，隧道纵向等效刚度有效率减小；

The test carrying out before and after strengthening shows the method is effective for enhancing integral rigidity and capacity of bridge.
加固前和加固后的荷载试验表明，采用这种加固方案提高了桥的整体刚度和承载力，达到了预期的效果。
