mso-hansi-font-family:"Times New Roman"">四、CBR "Times New Roman"">浸水膨脹附件試驗(yàn)原理:
mso-hansi-font-family:"Times New Roman"">試驗(yàn)時(shí),按路基施工時(shí)的含水量及壓實(shí)度要求在試筒內(nèi)制備試件;為了模擬材料在使用過(guò)程中的最不利狀態(tài),加載前飽水4 mso-hansi-font-family:"Times New Roman"">晝夜;在浸水過(guò)程中及貫人試驗(yàn)時(shí),在試件頂面施加荷載板以模擬路面結(jié)構(gòu)對(duì)土基的附加應(yīng)力;貫人試驗(yàn)中,材料的承載能力越高,對(duì)其壓入一定貫人深度所需施加的荷載越大。
