摘要
通过对焦晋高速公路孤山隧道中机制砂代替黄砂的技术可行性、经济可行性和实施可行性三方面的研究分析,结果表明,机制砂代替黄砂技术可行、经济节省、实施可靠,值得进一步推广使用。
Combined with Gushan tunnel work in Jincheng-Jiaozuo expressway project the substitution of yellow sand by machine-made sand is analyzed from three aspects： technical, economic and operable feasibilities. Comparison results show substitution of yellow sand with machinemade sand is practicable in above three aspects, which is worthy of being popularized.
