摘要： <正>以贵州省铜仁地区63块杨树固定标准地为研究对象，调查了I-69杨（Populus deltoids Bartr. cV. ‘Lux’）在不同立地条件下的生长状况。结果表明：随着坡度的增大，I-69杨的胸径、树高和蓄积均减小，从阳坡、半阳坡、半阴坡到阴坡，其胸径、树高和蓄积依次减小，且在阳坡、阴坡间差异显著；I-69杨上坡和下坡地生长状况差异也显著，下坡的生长状况好于上坡。与生长最差的荒地相比，退耕地上的杨树生长最好。随着土层厚度的增加。I-69杨胸径、树高、蓄积均增大，随着土壤密度的增大，杨树胸径、树高和蓄积均减小。

Abstract: The CFG pile construction method was introduced. Quality of CFG pile was analyzed. The CFG complex base bearing test was carried on. The results showed that the CFG pile continuity and strength complex base bearing satisfied the design requirements. The construction quality was good and guarantees the CFG pile complex base effectiveness on strengthening. It was a beneficial attempt that the CFG pile compound base technology had been applicated in deep soil soft base treatment of highway bridge head.
