水上浅层折射和反射波联合勘探应用研究

APPLICATION OF JOINT EXPLORATION METHOD OF SHALLOW SEISMIC REFRACTION AND REFLECTION WAVES ON WATER

  • 摘要: 用浅层折射和反射联合勘探方法在京─沪高速公路沂河桥址区进行隐伏断层和岩性垂直分带探测试验,试验是在宽约400m的水面上进行的。工作区第四系沉积层和下伏基岩对采用纵波速度作为探测物理量是敏感的,采用ES-2401高分辨率数字地震仪和"五小二高"的工作方法,全方位拾取折射和反射波信息,强化地质推断解释的可靠性,探测试验取得了良好的效果。

     

    Abstract: Prospecting test of hidden fault and vertical lithological analysis was carried out by using joint exploration method of shallow seismic refract and reflect waves at Yihe river bridge seat along Beijing-Shanghai expressway. The prospecting test was conducted on water, which is about 400 meter wide. Quaternary sediment and subterrane within working area are sensitive to longitudinal wave velocity, which is the detected physical parameter. Authors use high resolution digtal seismograph ES-2401 and adopt the working method of "five small and two high, and pickup information of refracted and reflected waves all directionly. These enhenced the reliability of geological interpretation, and prospecting test achieved good results.
