Haveing the benefit of vibratory roller and bulldozer , it easily bulldozes and compacts piles of garbage 將振動(dòng)壓路機(jī)和推土機(jī)功能有機(jī)結(jié)合起來,便于把成堆的垃圾推平后壓實(shí)。
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(duì)人工復(fù)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(duì)應(yīng)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(shí)際地源熱泵系統(tǒng)為例,在全年逐時(shí)負(fù)荷計(jì)算的基礎(chǔ)上,對(duì)大面積密集型樁埋換熱器管群周圍土壤的換熱特性進(jìn)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(yàn)橋設(shè)計(jì)使用壽命100年的要求,確定出高耐久性混凝土的設(shè)計(jì)控制指標(biāo),基于最緊密堆積原理和最佳漿骨比原理對(duì)橋梁的墩柱、蓋梁、預(yù)制箱梁和橋面板用高耐久性混凝土的配合比進(jìn)行設(shè)計(jì),并對(duì)其施工應(yīng)用技術(shù)進(jìn)行了研究。
