摘　　要：月球基地建设面临高真空、强辐射、极端温度等苛刻环境条件和资源受限约束,具有重要的科研价值。针对未来月球科研站的建设需求,本文采取上行资源与月壤原位资源相结合的建设思路,对月球基地构型、建筑构件、设备、能源以及建造方法进行了研究,并对成型工艺及基础性能进行了初步验证。针对建筑物和构筑物外层围护结构施工,提出了一套利用充气气囊、3D打印月壤砖和月壤袋三者结合的新型技术方案,并设计了相应的具有榫卯结构的月壤砖和拱轴线骨架形式的夹芯结构月壤袋。研究表明,内拉+外约束形式制作的月壤袋,拱顶承载力1 kN,构件尺寸误差约9.5%;3D打印月壤混凝土平均抗压强度为31.6 MPa,平均劈裂抗拉强度为2.0 MPa,达到了C20混凝土强度水平。月壤3D打印技术可为月球基地建设提供一种可能的发展途径。The construction of a lunar base faces harsh environmental conditions such as high vacuum,strong radiation,and extreme temperatures,as well as resource constraints,which holds significant scientific research value.In response to the construction requirements of future lunar research stations,this paper adopts a construction approach that combines upstream resources brought from the earth and in-situ resources available on the moon.And the lunar base configuration,architectural components,equipments,energy sources,and construction methods are investigated,the preliminary validation of the formability and fundamental performance are conducted.For the construction of the buildings and their outer enclosure structures,a novel technical method is proposed by utilizing inflatable membranes,3D printed lunar regolith bricks and lunar regolith bags,corresponding lunar regolith bricks with mortice and tenon structure as well as sandwich structure lunar regolith bags with arch axis are designed.The results indicate that the lunar regolith bags produced through internal tension and external constraint can withstand a load of 1000 N,with a component size error of approximately 9.5%.The average compressive strength of 3D printed lunar regolith concrete is 31.6 MPa,and the average tensile strength is 2.0 MPa,reaching the strength level of C20 concrete.This lunar regolith 3D printing technology offers a potential pathway for the construction of lunar bases.
