摘　　要：以阳泉市某国道黄树岩隧道工程为研究对象,在充分利用初勘地质资料的基础上,采用工程地质调绘、工程物探、钻探和室内岩土试验等勘察手段,对场地的工程水文地质条件进行了综合勘察,特别是在物探解译富水地块做了细致的研究,经综合分析发现隧道选址工程地质条件复杂,稳定性较好,适宜项目建设,隧道工程大小里程端洞口及左右线边坡稳定性均较差,应开展专项治理设计,为后续隧道详细设计和施工方案确定提供可靠的地质依据。This article takes the Huangshuyan Tunnel project on a certain national highway in Yangquan City as the research object.Based on the full utilization of preliminary geological data,comprehensive exploration of the engineering hydrogeological conditions of the site was carried out using surveying methods such as engineering geological filling,engineering geophysical exploration,drilling,and indoor geotechnical testing.Especially,detailed research was conducted on the interpretation of the rich water block by geophysical exploration.After comprehensive analysis,it was found that the geological conditions for tunnel site selection are complex,with good stability,and suitable for project construction.The stability of the tunnel engineering's large and small mileage end openings and left and right side slopes is poor,and special treatment should be carried out to provide reliable geological basis for the subsequent detailed design and construction plan determination of the tunnel.
