EPS 保温板垫层在红旗水库护坡中的应用

摘要

Through the application of contrast polystyrene insulation cushion( EPS) and gravel cushion solution in Hongqi reservoir upstream concrete slab revetment of Liaoning province, with the analysis of prototype observation test and data for three years, EPS insulation board replacement sand gravel cushion has been put forward to use as slope protection, and which is feasible in northern cold area .This technology can effectively reduce freezing depth of the soil under the slope.It can reduce the frost heave deformation and solves the problem of frost heaving of the dam slope.%通过对辽宁省红旗水库上游混凝土板护坡下应用聚苯乙烯（简称EPS）保温板垫层和砂砾石垫层方案对比，经过三年的原型观测试验及数据分析，提出在寒冷地区使用EPS保温板替代砂砾石作为护坡垫层的可行性。该技术能够有效降低护坡下土体冻结深度，减少冻胀变形，解决了坝坡的冻胀问题。
