摘要21世纪人类全面进入了海洋经济时代。海洋资源的开放利用已为全世界所重视，中国是海洋大国，拥有18000多公里绵长的海岸线，有着富饶的海洋资源，然而海洋资源的开发利用首先必须依赖于海岸与近海工程。同时海洋的环境条件十分恶劣，海岸工程的设计理论与建造技术必须保证安全可靠，防波堤作为海岸防护工程，必须能在波浪、潮汐等荷载复杂多变的环境中结构稳定、安全可靠地运行。由此可知，防波堤的变形监测与分析对海岸工程系统结构的综合安全性和风险的分析是十分重要的，对沿海经济地区的保护乃至发展我国蓝色国土有着积极的意义。

Abstract
21st century,human full access to the Marine economy. land resource has been difficult to meet the needs of the development of human society,The open use Marine resources has been paid great attention in all over the world,China is a maritime power,With more than 18000 km long coastline , has the rich Marine resources,However, Marine resources development and utilization must first rely on Yu Haian and offshore engineering.At the same time, the ocean environment condition is very bad,Coastal engineering design theory and construction technology must guarantee the safe and reliable,Must load the complex environments, such as wave, tidal structure stable, safe and reliable line operation."Accordingly,Deformation monitoring and analysis of the breakwater of coastal engineering system structure of integrated security and risk analysis is very important,The protection of coastal economic area and even the development of our country blue territory is of positive significance.
This topic is based on the general small coast protection engineering deformation monitoring data processing and analysis, comprehensive consideration of economic benefit in practical projects and accuracy requirement,At the same time meet the required load as coast protection engineering ability and the project life cycle.Through the study of the multiphase of Dongtou Wenzhou a breakwater monitoring data as the foundation,Using the method of drawing for the settlement of breakwater, inclination, horizontal displacement, horizontal deformation, settlement deformation rate of deformation, acceleration of technical indicators of line trend chart,And a significant settlement deformation curves for settlement,Analysis of the settlement and deformation behavior of the breakwater, sums up the law of settlement of breakwater,Combined with the external environment condition, analysis the relationship between each other, clear main influencing factors of settlement of breakwater,And on the basis of coastal engineering protection measures and the deformation principle of hydraulic structure, put forward the effective measures of reducing subsidence deformation.
Key words： Deformation monitoring, data processing, analyze , coastal protection
