摘要以承受竖向松弛地压的两车道公路隧道衬砌为原型，按照1/5比例尺制作NC衬砌、RC衬砌、ECC衬砌和R/ECC衬砌四种衬砌模型并进行承载力试验。针对1/5 NC模型衬砌设计ECC、R/ECC和RC三种套拱加固方案。随后基于塑性损伤模型建立NC和ECC衬砌计算模型，在通过与试验比较验证有限元模型可靠性的基础上，开展3种套拱加固不同损伤NC衬砌的数值模拟试验，以此分析3种套拱加固下不同损伤衬砌的力学行为及其加固效果。研究结果表明：ECC，R/ECC衬砌的韧性和延性明显优于传统NC衬砌，其中R/ECC衬砌呈现出较优的承载能力和变形性能。3种套拱加固方案中，R/ECC套拱加固效果优于ECC或RC套拱加固，且R/ECC套拱加固对不同损伤状态下的NC衬砌均有明显加固作用，对较严重到严重损伤NC衬砌的加固效果最佳；ECC套拱适用于轻微损伤到较严重损伤NC衬砌的加固；RC套拱主要适用NC衬砌损伤极严重情况。所得结论可为ECC在隧道维修、加固工程中的应用提供依据。

Abstract：Four kinds of 1/5 scale model linings have been designed based on the normal two-lane highway tunnel linings under vertical soil pressure，which are normal concrete(NC)，reinforced concrete(RC)，ECC and reinforced ECC(R/ECC) linings. Vertical loading tests have been done on the four linings. ECC Arch，R/ECC Arch and RC Arch strengthening were designed for 1/5 NC model lining. Subsequently，FE models of the NC and ECC linings were established based on the damaged plasticity model. After the FE models were validated with comparing the numerical and test results of NC and ECC linings，the numerical simulations on ECC，RC and R/ECC arch strengthened damaged NC linings with different damaged levels were carried out. The results show that the toughness and ductility of ECC and R/ECC linings are obviously better than the traditional NC lining，whereas the R/ECC lining gave better load-bearing and deformation capacities. R/ECC arch strengthened NC lining gave the best load-bearing capacities and the largest displacement，and it was mostly suitable for the NC linings from severely to seriously damaged level. Nevertheless，ECC arch strengthening method is suitable for both slightly and severely damaged linings. RC arch strengthening method is mainly suitable for the extremely damaged NC linings. Above conclusions can provide the basis for the application of ECC in tunnel maintenance and strengthening.
