公路桥梁对生态环境的影响及其保护对策

Impact on the Ecological Environment of Highway Bridges and Protection Strategy

公路桥梁的建设大大促进了交通体系的完善和发展,但是在建设和运行期间会对周边生态环境和生态系统产生一定的负面影响,随着我国社会对生态环境重视程度的不断增强,桥梁对生态环境的影响和相应保护对策也成为摆在桥梁工作者面前的一项重要任务,首先从桥梁改变生物生境、生物阻隔、局部小气候等方面分析了公路桥梁对生态环境的不利影响,然后从桥梁的建设运营理念、规划设计、桥梁施工过程控制、合理的桥梁绿化等方面对生态环境保护进行了探讨。

Construction of highway bridges has greatly promoted the improvement and development of the transport system,however,some negative effects on surrounding ecological environment and ecosystem will be caused during the construction and operation. As there is growing emphasis on the ecological environment in China,the impact on the ecological environment of highway bridges and protection strategy have become an important task placed in front of the bridge workers. Firstly,this paper analyzes negative impact on the ecological environment of highway bridges from change of biological habitats,biological barrier,and local microclimate of the bridge. Then this paper discusses ecological environmental protection from the construction and operation concepts,planning and design,bridge construction process control and reasonable greening of the bridge.
