摘要
结合国内一些研究思路及研究成果,依据多年现场实地工作经验,针对碎石土渗透性能展开研究。选取九江县戴山某滑坡的碎石土,进行样本重塑,分别改变碎石比例、空隙比、颗粒大小等条件设置多种试验样本,并设计对比试验方案。探究碎石比例、孔隙比、碎石颗粒大小对碎石土渗透性能的影响,采用对比分析的方法分析其试验数据,得到相应的函数变化关系,并分析小颗粒土流失情况。其结论可为水利工程建设及维护提供参考。
Some research ideas and research results in China are combined. The permeability of gravel soil is studiedaccording to field work experience for many years. The gravel soil of one landslide in Sanxia Reservoir area is selected forsample remolding. The gravel ratio, void ratio, particle size and other conditions are respectively changed for settingvarious test samples. Comparative test plans are designed. The influence of gravel proportion, void ratio and gravel particlesize on gravel soil permeability is explored. Comparative analysis method is adopted to analyze the test change curve among gravel ratio, void ratio, gravel particles size and gravel soil permeability coefficient is obtained in turnSmall particle soil erosion is analyzed, thereby providing reference for water conservancy project construction andmaintenance.
