A quasi - elastic method was proposed to decide the maximum load of rigid pavements under static load on the basis of experiments of reduced scale slabs , which was the key point for the similitude law to be used practically 在此基礎(chǔ)上給出了基于縮尺板試驗(yàn)的確定剛性路面板靜載下的極限荷載的半彈性方法。這是相似規(guī)律能應(yīng)用于工程實(shí)際的關(guān)鍵一步。
The specified works finished are listed : 1 . with experimental load - displacement curves and acoustic emission technology , it was found that the material shows pseudo - plastic behavior under tensile loads and quasi - elastic behavior under the flexural loads 通過斷裂試驗(yàn)的載荷位移曲線和聲發(fā)射檢測,發(fā)現(xiàn)了該材料的切口試樣在拉伸載荷作用下表現(xiàn)為偽塑性的特征;在彎曲載荷作用下表現(xiàn)出準(zhǔn)脆性的特征。
The calculated double differential cross section of the new model is compared with experimental data and previous scdw calculations with single particle model . the calculated cross sections are larger than those given by previous calculations at backword and forward angles and smaller than those given by previous calculations near the quasi - elastic scattering ( qes ) angle . the agreement with experimental data is much improved 新模型的雙微分截面計(jì)算結(jié)果與實(shí)驗(yàn)值以及以前采用單粒子殼層模型時的計(jì)算結(jié)果進(jìn)行了比較,表明cdfm模型的引入對scdw模型的計(jì)算結(jié)果有較大的改進(jìn),使其在大角度和極小角度區(qū)域有所增大,在準(zhǔn)彈性散射角附近有所減小,從而能更好地與實(shí)驗(yàn)值相符合。
