摘　　要：以高海拔宇宙线观测站(LHAASO)水切伦科夫探测器(WCDA)-水池底部HDPE土工膜施工为例,阐述了针对高寒地区负温条件下土工膜施工中存在的高立面、凸起面、拐角部位狭小空间作业等制约因素进行的施工措施研究与应用,保证了土工膜施工质量,加快了施工进度,节约了施工成本,所取得的经验可为类似工程提供借鉴。In this paper,the HDPE geomembrane at the water pool bottom of the high altitude Cosmic Ray Observation Station(LHAASO)water Cherenkov probe(WCDA)is taken as an example.In the cold area of negative temperature,through the study of a variety of measures,the high elevation,convex surface,corner position and narrow space operation constraints were overcome in the construction of geomembrane,and the construction quality of geomembrane was ensured,the construction progress was accelerated,and the construction cost was saved,which could provide reference for similar projects.
