摘要：

Numerous research efforts based on a wide variety of ground classification systems have been developed following Reference 3 from 1946, and it is beyond the scope of this article to discuss the results of those efforts. However, as previously noted, ground load in and of itself is almost never the controlling mechanism for the type of tunnel lining that needs to be designed as part of the finished facility. Final tunnel linings are typically designed to accomplish long-term functional, serviceability, and durability requirements rather than to resist intense internal or external loading conditions. Once a final lining has been designed based on those considerations, that lining can be analyzed to make certain that it has sufficient structural capacity to safely support soil loads expected following construction. Part 2 of this article will cover tunnel lining analysis and present recommendations for modeling and capacity calculations. © 2023 Concrete International. All rights reserved.
