Seismic survey is a new method used to civil engineering area in recent years. it was widely applied to survey or detecting of roadbase, dam base, foundation of building, tunnel, river bed, lake bed and etc. the chief methods are reflection method, refraction method, wave velocity testing, surface ware survey and transverse wave suivey. seismic survey can divide different layer, measure the incidence of sediment stratum, detect the structure of rock, test the handle effect of surface wave survey, we can calculate the carrying capacity of foundation and other mechanical parameters. this technique can give service to some big engineering departments such as highway developing company, survey design company, water supply company, plan bureau, construct bureau etc
應用於工程的主要方法有反射波法折射波法波速測井面波法及橫波勘探等。地震勘探能詳細劃分地層高精度地確定沉積地層的傾角能夠準確探明巖體構造褶皺斷層破碎帶裂隙帶對于回填工程路基壩基，地震勘探可以檢測其回填處理效果對于隧道工程，可以探測隧道洞體的圍巖分類及洞口地質情況利用面波勘探所得到的瑞利波速度，可以準確推算地基的承載力動彈模量等力學參數。 -
The analyzed results are as follows : the late 1960 ' s cutoff of riverbends increased both the runoff amount and the sediment transport amount of the lower reach of jingjiang river, while the sediment deposition decreased in the lkngting lake area ; after the mid 1980 ' s, both the middle reach of yangtze river main stem and the dongting lake occurred a trend of decreasing annual sediment transport as a result of decreasing sediment releasing from the upper reach of yangtze river ; and in the recent 3 years ( 2003 - 2006 ), the three gorges reservoir first impoundment additionally reduced the sediment concentration in the middle reach of yangtze river flow with a long time, so a distance would be quite long for suspended sediment recovery, but the distance for bed - material load of suspended sediment recovery would be quite short
分析結果表明： 20世紀60年代下荊江裁彎后，三口（松滋口、太平口、藕池口）分流分沙減少，下荊江徑流量和輸沙量相應增加，洞庭湖泥沙淤積減少； 80年代中期以後，長江中游幹流及洞庭湖出口的年輸沙量呈減少趨勢，城陵磯至武漢河段河床由淤積轉為趨向沖淤平衡；三峽工程初期蓄水運用后，長江中游含沙量沿程恢復距離較長，但床沙質部分恢復距離相對較短。 -
