本文是在大瑶山隧道复合式模型试验研究基础上,对具有超挖回填层的复合式衬砌作了进一步的模型试验。分析了超挖回填层和不同回填材料对复合衬砌模型结构承载力的影响.提出的结论可供隧道设计、施工参考。
Based on the compound model test of Dayaoshan Tunnel, this paper makes a further model test on the composite lining with over-excavation backfill. The effects of overdrafted backfill and different backfill materials on the bearing capacity of composite lining model are analyzed, and the conclusions can be used for tunnel design and construction reference.
