摘　　要：核电站的联合泵房是一个综合性、多功能的大型构筑物,涉及核电系统多达几十个,是核电站一个非常重要的子项。其主要功能为:为凝汽器提供必要的冷却水量,为整个核电站提供消防水等功能。联合泵房运行的正常与否直接关系着核电站的安全。联合泵房的底标高非常深,是整个核电站最深的构筑物,因此联合泵房的负挖,是整个核电站建造过程中最危险、最有挑战性的工作。本文通过对某核电站2×1100 MW机组联合泵房成功负挖施工技术的总结,对同类项目具有一定的借鉴和参考价值。The combined pump room of nuclear power plant is a comprehensive and multifunctional large structure,which involves dozens of nuclear power systems,and is a very important sub-item of nuclear power plant.Its main functions are as follows:providing necessary cooling water for the condenser,providing water consumption for the whole nuclear power plant,etc.The normal operation of the combined pump room is directly related to the safety of a nuclear power plant.The bottom standard of the combined pump room is very deep,and it is the deepest structure of the whole nuclear power plant,so the negative excavation of the combined pump room is the most dangerous and challenging work in the construction process of the whole nuclear power plant.This paper summarizes the successful negative excavation construction technique of a 2×1100 MW overseas nuclear power plant,which has certain reference value for similar projects.
