2、渣的力學(xué)性能及壓實特性進行分析,總結(jié)了宕渣的基本特點:其次,通過對現(xiàn)用壓實質(zhì)量檢測方法的研究,總結(jié)其存在缺陷并提出了綜合檢測法一考慮級配灌砂法和壓實沉降差法相結(jié)合的方法;最后引入模糊綜合評判的數(shù)學(xué)方法對檢測結(jié)果進行評定,以更科學(xué)地對宕渣壓實質(zhì)量作評、,定,37礦經(jīng)過現(xiàn)場試驗的檢驗,證明這種方法比原有的檢測手段更為科學(xué)、精度更高,更確切地反映了路堤實際壓實度,對公路工程質(zhì)量的提高具有較大工程實際意義和推廣應(yīng)用價值。本文所提出的方法完善了現(xiàn)有公路工程質(zhì)量評定標(biāo)準(zhǔn)。關(guān)鍵詞:路堤宕渣壓實檢測方法模糊綜合評判l(wèi)塑堅查堂墮主蘭垡絲塞
