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 ,探测试验取得了良好的效果
A shallow seismic refraction and reflection joint exploration method was used to test the concealed faults and stratigraphic division in the Shuhe Bridge Area of Beijing-Shanghai Expressway. The experiment was carried out on a water surface of about 300 m in width. Using the ES-2 4 0 1 high-resolution digital seismograph and the “Wu Xiao Er Gao” method of work, the comprehensive utilization of refraction and reflected wave information to improve geological inferred interpretation Reliability, sounding test has achieved good results
