由于地下洞室内空间有限，而大型核岛设备尺寸较大，在受限的地下空间进行混凝土施工和大型设备安装，是地下核电厂建设可行性研究必须要解决的关键问题。针对地下核电厂混凝土施工及大型设备安装的特点，开展了地下核电厂房洞室混凝土衬砌、反应堆厂房安全壳混凝土施工和大型核岛设备安装的相关技术研究，首次提出了适合地下核电厂混凝土施工和大型设备安装的技术方案，并对相关技术方案实施的可行性进行了论证，为地下核电厂后续的研究和工程实践提供了理论依据。%Due to large size of nuclear island equipment and limited interior space of underground cave, so the concrete con-struction and large equipment installation in the limited space is the key problem to be solved in the feasibility study of under-ground nuclear power plants construction. In view of the features of concrete construction and large equipment installation for un-derground nuclear power plants, the research on technology of concrete construction of underground cavern lining and nuclear re-actor containment as well as the installation of large-scale nuclear island equipment were carried out. And the technical solu-tions of concrete construction and large equipment installation were firstly proposed;the feasibility of relevant technical solutions implementation was also demonstrated, all of which can provide technical support for subsequent research and engineering prac-tice of underground nuclear power plants.
