| 中文摘要: |
| 地震记录质量的好坏极大地影响地震方法解释的可靠程度.在岩溶地区复杂地质条件下,为了获取高质量的记录,合理地选择地震方法,合适地布置测线,尽一切努力来压制干扰,是取得探测成功的关键.探测实例表明,在覆盖层厚度不超过20m的条件下,浅层地震反射法、折射法联合探测可获得良好的地质效果.作为一种有效的探查技术,等偏移横波(SH)反射法具有探测迅速,易于探测土洞、地下岩溶裂隙带的特点. |
| 英文摘要: |
| The reliability of seismic methods was strongly dependent upon record quality. In order to acquire good records, it was very important for successful detections to select exact seismic methods, arrange suitable surveying lines, and suppress noises by all means in karst areas with complicated geological conditions. The case studied showed that good geological results can be achieved by using joint exploration method of shallow seismic reflection and refraction waves in the condition of overburden thickness variation between 0 and 20m. As an effective investigation technique, common-offset SH reflection method can be carried out fast in the field and easy to detect caves and underground karst fracture zones. |
