针对工程中经常遇到的岩面较高的地质情况,在引桥墩的设计方案中首次采用将墩台分为2级的组合结构。此组合墩台.因缩短力臂从而减小大水平力作用下桩所承受的弯矩,避免以往斜桩难以站稳、普通直桩在水平力作用下产生大弯矩的不足。结合工程实例,介绍组合墩台的结构型式和工程应用情况,并利用大型有限元软件ANSYS建立模型,对桩的位移、内力等进行详细分析。计算结果表明,组合墩台结构型式合理可靠。 相似文献

The release of captive dolphins (Tursiops aduncus) from South Korean marine parks, which occurred in 2013, 2015, and 2017, is described and evaluated for its usefulness for conservation of coastal ecosystems. The campaign to free the dolphins created a flagship species, uniting the efforts of national government agencies, local government, and NGOs. However, the Korean management agencies framed the release as a species-specific conservation intervention, while the NGOs brought forward welfare-based demands for the curtailment of cetacean captivity. We argue that the release of the Korean dolphins changed the policy climate, to facilitate two major policy changes: revision of anti-whaling regulations to prohibit capture of cetaceans for exhibit, and improvement of regulations for rescue, rehabilitation, and release of stranded marine animals. Tradeoffs between welfare and conservation concerns are described in terms of risk for the management agency, welfare for the animals, and feasibility of a continued commitment to maintain the viability of the dolphin stock in the wild. The release of captive animals to their native range relies on a single-species conservation focus which poses little risk for management agencies but does not guarantee their continued commitment. 相似文献
