摘　　要：由于风化料的类别较多,致使其工程性质各异,结合新街河水库工程对风化料的特性进行了试验研究,分析风化料基本特性(颗粒组成、比重、液塑性,土的击实、抗渗、强度等),证明风化料作为防渗土料,压实性能、防渗抗渗性能好,抗剪强度高,具有施工简易、节约劳动力、节约材料等优点,试验结果表明风化料是一种修建防渗体较为理想的筑坝材料。The engineering properties of weathered materials vary due to their various categories.In this paper,the characteristics of weathered material are tested and studied in combination with Xinjiehe Reservoir Project.The basic characteristics of weathered material,such as particle composition,specific gravity,liquid plasticity,compaction,seepage resistance and strength of soil,are analyzed.It is proved that weathered material as impervious soil material has good compaction,impervious and impervious properties,high shear strength,simple construction,labor saving and material saving.The test results show that weathering material is an ideal material for dam construction.
