摘要
用浅层地震折射和反射联合勘探方法在京—沪高速公路沭河桥址区进行隐伏断层和层位划分探测试验。试验是在宽约 30 0m的水面上进行的 ,采用ES- 2 4 0 1高分辨率数字地震仪和“五小二高”的工作方法 ,综合利用折射和反射波信息 ,提高地质推断解释的可靠性 。
Prospecting test of hidden faults and layer division was carried out by using joint exploration method of shallow seismic refraction and reflection waves at the bridge seat of Shuhe River along Beijing—Shanghai Expressway.The prospecting test was conducted on water surface which is about 300 m wide.The authors used high resolution digtal seismograph ES-2 401 and adopted the working method of “five smalls and two highs”,and picked up information of refracted and reflected waves in all directions.These measures enhanced the reliability of geological interpretation,and the prospecting test achieved good results.
