| 摘 要： | 为了对昆明市活断层构造的深浅关系有更深入的了解,在浅层地震反射勘探的基础上,布设了一条东西向、横跨昆明盆地的中深层探测剖面KM4测线,通过对测线参数的试验与分析,确定了适合昆明盆地反射地震勘探的施工参数,采用该施工参数,开展了有效勘探深度为2～3 km的中深层反射地震勘探,确定了目标区隐伏活断层在盆地深部与盆地基底展布的异同及空间关系,探测到了昆明盆地深部断层的基本位置,确定了浅部断层与盆地基底断裂间的关系.对该测线的设计和参数采集试验分析,为城市和山区的活断层探测提供了宝贵的经验.

| Abstract: | In order to have a further understanding for the distribution of depth of active faults in Kunming,we deployed an EW-trending KM4 exploration line crossing mid-deep layer detection profile in Kunming Basin on the basis of the exploration of shallow seismic reflection.Through the experiment and analysis of the construction parameters,we determined the parameters fit for reflection exploration of Kunming Basin,carried out mid-deep layer seismic reflection exploration(2-3 km effective exploration depth),and ga... |
