Haveing the benefit of vibratory roller and bulldozer , it easily bulldozes and compacts piles of garbage 將振動壓路機和推土機功能有機結(jié)合起來,便于把成堆的垃圾推平后壓實。
Application of cpt technology in the loess area , the bearing capacity of artificial composite ground is determined . moreover , the correspondence relationship between the curve feature of cpt and the compact effect of lime - mud soil compact pile is discussed 論述了靜力觸探( cpt )技術(shù)在黃土地區(qū)對人工復合地基承載力的確定,以及靜力觸探曲線特征與灰土擠密樁擠密效果的對應關(guān)系。
With an actual ground source heat pump system example , based on the hourly calculation of annual cooling and heating load , carries out numerical simulation on heat transfer characteristics of the soil around compact pile - buried underground heat exchangers with large land area 摘要以一實際地源熱泵系統(tǒng)為例,在全年逐時負荷計算的基礎(chǔ)上,對大面積密集型樁埋換熱器管群周圍土壤的換熱特性進行了數(shù)值模擬。
Considering the past research results , frost resistance of concrete using portland cement , and the designed service life of 100 years of testing bridge , the control indexes of high durability concrete are defined in this paper . mixture proportion of concrete used in pier column , coping , precast box beam and plate of bridge is designed based on the compact pile theory , and construction technique is studied also 結(jié)合課題組以往的研究成果,根據(jù)試驗橋設(shè)計使用壽命100年的要求,確定出高耐久性混凝土的設(shè)計控制指標,基于最緊密堆積原理和最佳漿骨比原理對橋梁的墩柱、蓋梁、預制箱梁和橋面板用高耐久性混凝土的配合比進行設(shè)計,并對其施工應用技術(shù)進行了研究。
