【摘要】 随着工程建设质量的提高和施工环境的日益复杂,物探技术的精度和可靠性的要求越来越高,单一的物探方法很难满足要求。本文采用地质雷达与地震映像法相结合的综合物探技术,以宜万铁路某一隧道内的岩溶及裂隙带的成功探测为例,证实了该方法在铁路隧道底部隐伏岩溶勘查中的可行性和有效性。更多还原

【Abstract】 With the improvement of the construction quality in project and the increasingly complicating of the construction environment,the demand of the accuracy and the reliability of geophysical technique becomes higher and higher.But it is difficult to meet the requirements of the single geophysical method.The paper adopting integrated geophysical technique of ground penetrating radar combination with seismic imaging method and using an application of the successful detection of the karst and fissure zone in a tunnel of Yiwan railway as example,confirms the effectiveness and feasibility of the method in the exploration of hidden karst in railway tunnel.更多还原
