加筋土施工工艺在膋头水电站施工中的应用

Application of Reinforced Earth Technique During Constructing the Pengtou Hydroelectric Power Station

加筋土是在土方回填中分层布置土工合成材料作为加筋,提高回填土体的承载力,减小回填土体的竖向和横向变形的一种施工工艺。文中以加筋土在膋头水电站中应用为例,通过对加筋土土料回填参数确定、施工工艺等方面的叙述,总结出了几点经验。

The reinforced earth is a kind of construction technique in which layer-arranged geosynthetics are used as reinforcement in earth filling works to raise the bearing capacity of backfill earth body and to decrease its vertical and lateral deformation. The paper takes the application of this technique during constructing the Pengtou Hydroelectric Power Station as an example, narrates determining backfill parameters of reinforced earth material and its construction technique, and summarizes some experiences.
