小山水电站混凝土面板堆石坝是我国寒冷地区已建同类坝型中的最高坝（坝高８５．３ｍ）。根据坝址地形、地质及气候条件，坝基和趾板开挖采用分层开挖和周边预裂方式；采石场采用深孔梯段微差挤压爆破技术；上坝施工道路分期、分层布置；采用较新鲜的安山岩级配料直接上坝，以减少冬季填筑坝体冻结深度；冰冻季节施工采用了不加水、薄层碾压技术。
The Xiaoshan Hydropower Station concrete faced rockfill dam is the highest dam (85.3m in height) in the same type of dam built in the cold area of China. According to the dam topography, geology and climatic conditions, the excavation of the dam foundation and plinth adopts the method of stratified excavation and surrounding pre-cracking; the quarry adopts the deep-hole benchlet differential extrusion blasting technology; the dam construction road is divided into stages Arrangement; using relatively fresh andesite grade ingredients direct dam, in order to reduce the freezing depth of dam filling in winter; the construction of the freezing season without water, thin layer rolling technology.
