根據山前帶的地震地質條件特點，本文主要研究了以下幾個方面的內容： 1 、對以往山前帶地震攻關成果開展調研工作，分析研究在山地山前復雜構造帶所採用的地震勘探採集技術的適用性； 2 、研究基於地震地質模型的復雜構造帶觀測系統目標設計方法：如何建立復雜構造帶的表層、深層地震地質模型，利用正演分析目標區的觀測系統；針對逆掩推覆體構造，如何分區分段有針對性設計觀測系統等； 3 、針對復雜地表條件的山地山前帶，如何選擇激發方式、參數，如何優選激發、接收環境，如何保證不同激發方式的資料能正常拼接； 4 、山前帶巨厚礫石區的表層結構調查技術及靜校正方法研究。Owing to complicated earth ' s surface condition such as the steep stratum outcropping of front - zone of mountain or the huge thick gravel stratum ' s overlay and earth ' s surface large undulation, complicated underground geology structure developed extremely such as thrust and overthrust nappe, and violent change of the lateral velocity, etc. in front - zone of mountain there are a series of problems such as serious secondary disturbance and low signal - to - noise ratio in seismic exploration gathering
由於山前帶高陡巖層出露或巨厚礫石層的覆蓋、地表起伏大等復雜的地表條件、逆沖和逆掩推覆等復雜地下地質構造發育、速度橫向變化劇烈等原因，造成了山前帶地震勘探資料採集存在次生干擾嚴重和信噪比低等一系列問題。Among the 130 debris flow valleys, dazhai gully suspends high on the up range of baihetan hydropower station, with an altitude over 970 m and a drop more than 350 m. gravels, mud and flood in this valley brings the construction site in great danger. 3 kilometers upriver from the mouth of dazhai gully, lies the haizi gully, which is also frequented by debris flows, but will be taken as the dumping site for the construction
庫區130條泥石流溝中大寨溝以溝口海拔970餘米的高程和350餘米的落差高懸于白鶴灘水電站的大壩上方，其溝內泥石流帶來的礫石、泥沙與洪水直接威脅著電站建設工地和樞紐的安全；緊鄰大寨溝溝口上游約3km的海子溝則為一條泥石流活動頻繁的溝谷，因其出口將作為水電站建設的棄渣場地，流域內的泥石流活動關系著水電站建設中棄渣場的安危。
