【Abstract】 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.更多还原
