摘要:
对于海岸工程所遇到的自然灾害,仅以加大结构尺度与结构强度的传统方法应对是不可取的。改变传统理念,通过改善工程与环境的关系,提高工程韧性是较合理的选择。韧性海岸工程以工程系统与环境相协调,具有吸收和适应自然力、灾害情况下维持其功能以及灾后可快速恢复的能力为特征。针对港口工程、海岸及港口防护工程建设提出了韧性工程实施策略及方法。以韧性工程理念对港口规划与平面布置、复杂环境下的码头结构及航道工程设计提出优化原则与方案。海岸及港口防护工程可采用多重防护、吸收性防护、变形型防护及生态型防护等类型,以改善工程与环境的适应性,增强工程韧性。

Abstract:
Natural disasters cannot be well-prevented by coastal works by selecting traditional methods such as the increment of structural sizes and strength. In comparison with the traditional concept, it is appropriate to improve the coastal resilience by coordinating the project with local environment. Coastal resilience works integrates the whole system with the environment and absorbs or adapts to natural force in order to maintain its functions under natural disasters, or quickly recover its performance after the disaster is gone. The resilience strategies and methods were recommended for port, coastal, and protective projects. Based on the concept of resilient engineering, the optimization principles and plans were proposed for port planning and plane layout, the design of berth structure, and channel in complex environment. In the protective works of coast and port, multi-protection, absorptive protection, deformation protection, and ecological protection can be used to improve the performance of the protective construction in harmony with local environment, and consequently enhance the engineering resilience.
