摘　　要："十三五"期间中国提出了"深海进入、深海探测、深海开发"的海洋战略。全海深载人潜水器即是"深海进入"的重要装备,其核心部件载人舱的材料选择、设计标准、制造工艺以及结构安全评判就成为需要解决的技术问题。论文针对超高强度马氏体镍钢C250制造的载人舱缩比结构模型,进行压力筒静水压力测试;并对结构应力、极限载荷和体积收缩率进行测试,以研究超高强度马氏体镍钢应用于深海载人舱的设计、计算与制造的可行性。In the period of 13 th five-year planning（2016 ～ 2020）, Chinese government put forward a strategy of ＂entering, exploring and exploiting the deep ocean＂. Full ocean depth manned submersible is one of the important equipment for the strategy. Manned cabin is a key component of the submersible, key issues such as material selection, design standard, manufacture process and safety assessment of the structure for the manned cabin are studied. Static pressure test for a scaled manned cabin built with Maraging steel（C250） is carried out, while structural stress, ultimate strength and volume shrinkage rate are measured. Feasibility of Maraging steel used in the design and manufacture of full ocean depth manned cabin is discussed.
