羊湖电站地处青藏高原温带半干旱地区，冬季昼夜温差大，风雪多，根据工程部位的不同特点分别制定了混凝土冬季施工技术措施．隧洞混凝土衬砌施工采用蓄热法即用洞内的正温地下水加热后拌制混凝土，对料场、料仓、拌合站、成品运输设备等采用防护保温措施．洞外混凝土一般不进行冬季施工，对个别部位的零星混凝土和已浇但需要防护的混凝土，按规定进行冬季施工和进行妥善的保温措施．
Yang Lake Power Station is located in the temperate semi-arid area of the Qinghai-Tibet Plateau, with large temperature difference between day and night in winter and heavy snowfall. According to different characteristics of the project site, concrete winter construction technical measures are formulated. Concrete lining construction of tunnel adopts the method of regenerative heating, that is, the concrete is mixed with positive temperature groundwater heated in the tunnel, and the protective and insulation measures are adopted on the material yard, silo, mixing station and finished transportation equipment. Concrete outside the cave is generally not for winter construction, the individual parts of the sporadic concrete and has been pouring but need to protect the concrete, according to the provisions of the winter construction and proper insulation measures.
