【摘要】 随着经济、城镇化建设的快速发展,查明拟建地下巷道位置、埋深、规模和走向,对于地基处理和基础设计显得十分重要。笔者针对城市特殊的场地条件和干扰环境,开展了综合物探方法探测城市地下巷道的可行性研究,提出了以瞬变电磁法为主,浅层地震反射波法佐证为辅的新型综合物探组合模式,并深入研究了其可行性和互补作用。实践表明,上述综合物探方法组合既可适应于城市地下巷道的探测精度,又具有压制来自城市干扰的优势,是行之有效地方法。更多还原

【Abstract】 In the light of special site conditions and interference environment of the city,the authors carried out the feasibility study of applying integrated geophysical exploration methods to detecting underground tunnels,put forward a new combined model for integrated geophysical exploration and deeply studied the feasibility and the complementary role.Practice shows that the combination of the integrated geophysical methods can meet the detection accuracy of the urban underground tunnel,and also has the advantages of suppressing interference from the city.It is proved that this combination is effective.更多还原
