十堰至天水高速公路磨河村隧道工程地质条件分析

通过对隧址区地形地貌、地层岩性、地质构造、岩土体工程地质特征等的调查,结合工程物探、地质钻探,岩体物理力学试验和地质测绘等勘察成果,分析了隧道洞身及进出口处围岩的稳定性,指出隧道施工过程中可能会遇到的工程地质问题,并提出了超前地质预报、支护、预防地质灾害、保护生态环境等施工措施和建议。

Analysis on Geological Conditions of Tunnel Engineering in Mohe Village of ShiyanTianshui Expressway

Through survey on geological characteritics, such as topography, lithology, geological structures and rock and soil engineer, combining with engineering geophysical, geological drilling, rock mechanics test of physical and geological mapping and other survey results, stability of tunnel body and rocks in the entrance of the tunnul and surrounding rocks has been analyzed. Engineering geological problemsIt which will be met in tunnel construction process have been pointed out, and some countermeasures are put forward, such as geological predication, support, preventing geological disasters and protecting the ecological environment.
