摘要
襄樊至荆州高速公路路基广泛分布有水敏性地层、古卵石层及坚硬致密岩层 ,给工程地质勘探工作带来很多问题。通过对上述三种地层地质特征的研究 ,探讨钻探方法的使用及新型泥浆的应用。
Water-sensitive formation, older gravel stratum and hard-compact rocks are spreading widely in the highway from Xiangfan to Jingzhou, which lead to difficulties in the engineering investigation. By studying geological characteristics of special stratam, the main points of optimized drilling operations are pointed out.
