| 摘 要： | 土体分散性会因为雨水或渗流作用导致水工建筑物出现管涌与冲蚀等渗透破坏，为此针对大安水利枢纽灌区工程中的冲蚀现象进行了土体分散性的研究。通过对土样进行颗粒分析实验，测定黏土矿物成分以及土样的物理化学性质，采用针孔试验、双比重计试验和交换性钠百分比3种试验方法鉴定土样分散性。经综合鉴定得出，所取大安地区土样均为分散性土，土样中大量的交换性钠含量和强碱性等是导致土样产生分散性的主要原因。

| Abstract: | The dispersibility of the soil leads to piping,erosion,infiltration and sabotage of water project in the condition of rain or seepage flow.Aiming at the erosion of Da'an irrigation area,the dispersibility of the soil was studied.At First,the soil samples grading analysis test were conducted and clay mineral composition and physicochemical characterizations were measured.Three test methods,namely,pin hole test,double hydrometer text and percentage of exchangeable sodium test were carried out to identify the ... |
