崩解泥岩的简易剪切装置研制及应用DOI: 10.14081/j.cnki.hgdxb.2018.04.01 Keywords: 简易剪切装置, 崩解泥岩, 干湿循环, 剪切强度simplesheardevice, disintegratedmudstone, drywetcycle, shearstrength. Abstract: 由于崩解后的泥岩材料属于一种含有砾石的黏性土,而目前对于这种土的剪切试验研究较少,且没有 较为适用并经济的剪切试验仪器.因此,本文设计了一种适合于测量崩解后泥岩土剪切强度的简易剪切装置, 该装置由围压荷载加载系统、围压荷载测量系统、垂直剪力加载系统3部分组成.该装置结构简单,设备材料 容易获取而且成本较低,适合在普通的公路实验室内使用.Sincethedisintegratedmudstonematerialbelongstotheclaysoilcontaininggravel,therearefewstudieson thesheartestofthissoil,andtherearenoeconomicalandapplicablesheartestinstruments.Therefore,thispaperde? signedasimplesheardevicesuitableformeasuringtheshearstrengthofdisintegratedmudstoneremoldedsoil.Thede? viceiscomposedofconfiningpressureloadingsystem,confiningpressureloadmeasuringsystemandverticalshearload? ingsystem.Thedevicehasasimplestructure,easyaccesstoequipmentmaterialsandlowcost,andissuitableforordi? naryhighwaylaboratories.
