规划新建核电厂建设厂址条件日益复杂,其排水隧洞工程建设中需综合考虑软弱土层、高水压、排水口实施等因素带来的影响,并在工程建设前期规划中合理布置隧洞线路与选择结构方案.为此采用工程类比法对同类工程进行调查研究,分别对隧洞不同埋深、不同衬砌结构方案等进行比选,对影响霞浦核电排水隧洞工程建设的部分因素提出应对措施,并据此确定了建设方案,为工程建设的顺利进行奠定了基础.
The site conditions for planning the construction of new nuclear power plants are becoming increasingly complex.During the construction of their water discharge tunnels,it is necessary to comprehensively consider the impacts of soft soil,high water pressure,and the implementation of the water discharge outlet in order to reasonably plan tunnel routes and select structural schemes in the early stages.Therefore,an engineering analogy method has been adopted to investigate and study similar projects,comparing and selecting different tunnel burial depths and lining structure schemes.Measures were proposed to address some factors that affect the construction of the Xiapu Nuclear Power Plant drainage tunnel project,and a construction plan was determined based on this,laying the foundation for the smooth progress of the project construction.
