为解决已建成运营的地铁与外部环境不协调和不能满足新的运营功能需求的问题,必要时需对运营地铁工程进行改扩建。以西安地铁已实施的几种土建相关改扩建工程(包括车站主体、车站出入口、车站风亭、车站小型附属构筑物)为例,对改扩建工程的背景、实施方案、实施效果、风险源及技术措施、运营保障措施、实施管理机制、投资及综合效益等方面进行分析和梳理。认为: 1)对地铁进行改扩建的方式是灵活多样的,应通过多角度比选出最佳改扩建方案; 2)实施前应充分论证和验算,将不利影响、实施风险、工程投资降到最低; 3)在乘客密集的公共区域施工作业,需加强运营管理,制定专项紧急保障方案,避免发生运营事故; 4)现缺少针对改扩建工程的施工及设计规范、标准,缺乏系统化的管理程序及机制,建议尽早形成地铁改扩建完善的建设程序、合理的管理机制。 相似文献

Janusz Mindykowski 《Maritime Policy and Management》2017,44(3):336-357
The paper deals with education of ship engineers as an integral part of maritime policy in global shipping. The central problem, how to reconcile technological advancement with training en route to improving safety, is defined. A complete conceptual model for solving a central question is formulated and described. At the beginning, a short analysis of technological advances and the need for training is presented. Next, the basic components of conceptual model, including implementation and assessment of new standards of competences for Electro-Technical Officers in the wake of Maritime Education and Training (MET) development are discussed. A key point of the assessment procedure is focused on the formulation of criterion defining the impact of new standards on the given processes characterizing a professional carrier development of seafarers. These processes, which mean certification process and recruitment of candidates to seafarer profession, are strongly linked with and influenced on MET development and improving the safety of shipping. Empirical application by pointing the Polish case study to the framework of conceptual model under consideration is shown and analysed. Finally, the future works as well as the concluding remarks are formulated and commented on. 相似文献

Coastal areas are under increasing pressure driven by demands for coastal space, primarily though population growth, in migration and the need for space for socioeconomic activities. The pressures and associated changes to the coastal environment need to be managed to ensure long-term sustainability. South Africa has enacted an Integrated Coastal Management Act (ICM Act) to facilitate dedicated management of its coastal environment. The implementation has been met with a number of challenges, primarily relating to financial and human capacity constraints, particularly at the local government level. Given that the ICM Act devolves powers to local government, it is imperative that implementation challenges be addressed. This paper focuses on KwaZulu-Natal, one of four South African coastal regions, which is a renowned tourist destination and home to 11.1 million people (Statistics South Africa 2015). This paper considers the state of coastal management, as well as implementation challenges being experienced at a local governance level, and highlights ways to address these. Data were acquired through questionnaire surveys and semistructured interviews. The Drivers-Pressures-State-Impact-Response (DPSIR) framework was used to identify relevant ICM issues and concerns and develop potential actions for improving the implementation of coastal management activities and the ICM Act. In the assessment of the ICM governance and implementation to date, a key concern identified was a general lack of coastal management knowledge among officials. It was specifically identified that knowledgeable management and capacity-building required championing from the provincial government in order to more efficiently and effectively implement the objectives of the ICM Act through an improved understanding of the coastal environment, its functioning and management. 相似文献
