【摘要】：本文針對(duì)沖擊壓路機(jī)在黃土地區(qū)的使用缺乏詳細(xì)的沖擊壓實(shí)技術(shù)規(guī)范,施工質(zhì)量控制方法也不成熟等施工關(guān)鍵問題,依托準(zhǔn)池鐵路實(shí)際工程地質(zhì)條件,利用鉆芯取樣方法,對(duì)YCT-25型沖擊壓路機(jī)在黃土路基中的補(bǔ)強(qiáng)使用進(jìn)行效果驗(yàn)證。結(jié)果表明:在2m范圍內(nèi),沖擊壓實(shí)效果明顯;經(jīng)壓實(shí)度檢測(cè),得出合理沖擊遍數(shù)為10遍;對(duì)于低液限黏土,土的含水率在ωopt-2%≤ω≤ωopt+4%這個(gè)范圍內(nèi),經(jīng)過沖擊壓路機(jī)補(bǔ)強(qiáng)作業(yè),黃土路基也能達(dá)到壓實(shí)要求。
[Abstract]:In view of the lack of detailed technical specifications for impact compaction and the immature construction quality control methods, this paper relies on the actual engineering geological conditions of quasi-pool railway and uses the method of sampling by drilling core, in view of the lack of detailed technical specifications for impact compaction in the loess area and the immaturity of construction quality control methods. The effect of reinforcement of YCT-25 impact roller in loess roadbed is verified. The results show that the impact compaction effect is obvious in the range of 2m, the reasonable impact times are 10 times after compaction testing, and for low liquid limit clay, the moisture content of the soil is within the range of 蠅 opt-2% 鈮，
