China's transportation infrastructure is facing severe challenges such as serious structural defects, short life, aging, and the absence of a long-life security strategy. Therefore, this paper complies the advancements in developed countries regarding these issues and proposes the overall objectives, strategic tasks, and related recommendations for constructing a long-life security system for Chi-na's transportation infrastructure. It also presents systematic research into construction of long-life security systems for transportation infrastructure. This research has a very significant strategic significance in ensuring the safe long-life service of transportation infra-structure and safe and smooth traffic arteries, supporting sustainable development of the national economy, protecting people's lives in a stable and orderly manner, and contributing to national security and social stability.%本文主要针对我国交通基础设施存在的结构病害严重、"短寿命"突出、"老龄化"日益凸显、长寿命安全服役面临严峻挑战等问题,借鉴发达国家的先进经验,提出了我国交通基础设施长寿命安全保障体系建设的总体目标、战略任务及相关建议,并开展了交通基础设施长寿命安全保障体系的系统研究和建设工作,对确保其长寿命安全服役和交通大动脉的安全畅通、支撑国民经济可持续发展、保障人民生活安稳有序、助力国家安全和社会稳定具有十分重要的战略意义.
