摘要: 通过对西藏主干公路沿线天然砂砾作为路用材料的调查,以气候类型为主要依据对西藏天然砂砾进行了分 区研究。根据西藏各分区天然砂砾的级配组成,采用特征孔径通过率法和细度模数法分析了西藏天然砂砾的粗细 程度,同时提出西藏天然砂砾的代表级配。

关键词: 西藏, 天然砂砾, 代表级配, 特征孔径, 细度模数

Abstract: Through the investigation of natural grit used as the matErial of the main arterial highway in Tibet,the region research on natural grit in Tibet has been carried out,which is manly based on the climate type. Accorrling to the gradation composition of natural grit at various districts in Tibit,the thickness of the natural grit in Tibet has been analyzed by the method of characteristic aperture passing rate and fineness modulus, Meanwhile, the representative gradation of natral grit in Tibet is proposed

Key words: Tibet, natural grit;representative gradation;characteristic aperture fineness modulus
