以金堆城钼业尾矿输送隧道工程地质勘察为例,采用分布式数字地震仪进行浅层地震法测试,较好地查明了地层、断裂构造,并根据波速进行了地质分段,为隧道岩体质量和工程地质围岩分类评价提供了较充分的分段依据,此分段方法经钻探、槽探及工程地质测绘验证,并在隧道施工时进行了现场确认,与现场实际情况基本吻合。在阐述了浅层地震反射波探测方法的基础上,引用浅层地震勘探成果较好地解决了隧道工程勘察中的分段、岩体质量指标和围岩稳定性评价等问题,对类似工程有一定的指导意义。
Taking the geological exploration of the tunnel engineering of Jinduicheng molybdenum tailings transportation tunnel as an example, a distributed digital seismograph was used to carry out the shallow seismic test, the strata and fault structures were well identified, and the geological segmentation was carried out according to the wave velocity. Tunnel rock mass quality and engineering geological classification of rock provides a more adequate basis for the sub-section by drilling, trenching and engineering geological mapping validation, and in the tunnel construction site was confirmed on the spot and the actual situation of the basic Anastomosis. Based on the description of the shallow seismic reflection wave detection method, the reference to the shallow seismic exploration results can well solve the problems in the tunnel engineering investigation such as sub-section, rock quality index and surrounding rock stability evaluation, A certain guiding significance.
