摘要
三维地震勘探成果数据包含丰富的三维地质信息,它保存了受地裂缝灾害影响而改变的地层结构、地球物理场信息变化的各类特征。本文利用因果岸三维地震勘探数据,分析了该区地裂缝的成因,对控制其形成的三个内因———粘弹性地层、古潜山起伏形态及含水砂层空间分布进行了半定量化分析,为地裂缝灾害易发区预测研究提供了依据。
3D seismic exploration data includes a lot of 3D geologic information. It keeps much variational information about strata structure and physical geography field, which is affected by ground fissure disaster. The mechanism of ground fissure was analysed by using 3D seismic exploration data in Yinguo＇ an area, Wuxi City. Three intrinsic factors of controlling ground fissure formation, which are the visco-elastic strata, bedrock waviness and spacial distribution of aquifer, were semi-quantitatively analysed and discussed. It is very important reference for forecasting research on ground fissure disaster formation.
