摘要: 以宁巧隧道工程为研究对象，基于地震易损性分析方法，在FLAC3D中建立了三维动力时程数值计算模型；通过Python语言进行二次开发，实现了易损性分析中增量动力分析方法的全流程自动化计算；给出了薄直中隔墙连拱隧道结构在有无钢带加固措施、2种地震波入射方向(水平与竖直方向)、2种围岩级别(Ⅳ与Ⅴ级)共8种不同因素组合下的易损性曲线，得到了结构在隧址区抗震设防烈度下的损伤概率；通过对比分析损伤概率评价了钢带加固措施的抗震效果及规律；通过大型振动台试验，对比相似模型结构在有无抗震措施下的破坏形态和损伤程度，验证了钢带加固措施的实际作用效果。研究结果表明：无论何种因素组合，钢带加固措施均能有效减小结构在不同损伤状态下的损伤概率，作用效果受围岩级别影响较大，受地震波入射方向影响较小；Ⅴ级围岩条件下，其轻微、中度、重度损伤状态下的损伤概率在地震波水平方向入射时分别减小了51.94%、41.29%、29.63%，在竖直方向入射时分别减小了55.68%、48.32%、35.29%；Ⅳ级围岩条件下，其轻微、中度、重度损伤状态下的损伤概率在地震波水平方向入射时分别减小了16.45%、11.19%、7.11%，在竖直方向入射时分别减小了12.23%、9.45%、7.49%；振动台试验中，使用钢带加固后的相似模型在最不利因素组合条件下的损伤程度明显低于无抗震措施结构；钢带加固措施能通过提高结构整体承载能力，有效地减少病害数量，降低结构损伤程度，提高结构抗震性能。Abstract: The Ningqiao Tunnel project was taken as the research object, and a three-dimensional dynamic time-history numerical calculation model was established in FLAC3D based on seismic vulnerability analysis method. The full-process automation calculation of the incremental dynamic analysis method in seismic vulnerability analysis was achieved through secondary development by Python. The vulnerability curves of the double-arch tunnel structure with thin and straight mid-partition wall under the eight different combinations of factors were given, including the measures with and without steel strip reinforcement, two directions of seismic wave incidences (horizontal and vertical directions), and two types of surrounding rock grades (Ⅳ and Ⅴ grades). According to the vulnerability curves, the damage probabilities of the structure at the tunnel site under seismic fortification intensity were obtained. The seismic performance and the pattern of steel strip reinforcement measures were evaluated by comparing the damage probabilities. The actual effect of steel strip reinforcement measures was verified by comparing the failure patterns and damage degrees of similar model structures with and without seismic measures based on a large-scale shaking table test. Research results show that regardless of the factor combination, the steel strip reinforcement measures can effectively reduce the damage probabilities of the structure in different damage states. The effectiveness is significantly influenced by the surrounding rock grade but less by the direction of seismic wave incidence. Under the Ⅴ grade surrounding rock condition, the probabilities of slight, moderate, and severe damages reduce by 51.94%, 41.29%, and 29.63%, respectively when the seismic waves are incident in the horizontal direction, and reduce by 55.68%, 48.32%, and 35.29%, respectively when the seismic waves are incident in the vertical direction. Under the Ⅳ grade surrounding rock condition, the probabilities of slight, moderate, and severe damages reduce by 16.45%, 11.19%, and 7.11%, respectively when the seismic waves are incident in the horizontal direction, and reduce by 12.23%, 9.45%, and 7.49%, respectively when the seismic waves are incident in the vertical direction. In the shaking table test, the damage degree of the similar model structure with steel strip reinforcement measures under the most unfavorable factor combination is significantly lower than the structure without seismic measure. The steel strip reinforcement measures can effectively reduce the number of diseases, lower the degree of structural damage, and enhance the seismic performance of the structure by improving the overall load-bearing capacity of the structure.
