经过实践检验得出,探查城市的活断层,即探查被沉积层覆盖的活断层之时,其得出的问题主要有两个,第一个问题是上断点层位有相应的局限性,它的作为活动性指标特性,是其局限性的主要影响因素;另外,在探测手段与方法之中,其分辨率以及有效的深度范围都存在相应的有限性。第二个问题是严重低估了地震的危险性,实际的上断点处对应的深度比探测过之后上断点的深度要小,导致活断层被漏掉,最近几年我国地震发生之后,破坏性非常大的原因也和这方面内容有关系。因此,要积极探查、深入实践从而积累相关的经验,这样经过深入讨论之后,将问题解决的可能性也会相应的增加。从两个方面对城市隐伏活断层探查与评价的相关问题进行了研究。
After practice, it is concluded that there are mainly two problems in the exploration of the active fault in the city, that is, the exploration of the active fault covered by the sedimentary layer. The first problem is that there are corresponding limitations in the upper fault point, Its characteristics as an indicator of activity are the main influential factors of its limitation. In addition, its resolution and effective depth range have corresponding limitations in the exploration methods and methods. The second problem is a serious underestimation of the danger of earthquakes. The actual depth at the upper breakpoint is smaller than the depth of the upper breakpoint after the exploration, leading to the active fault being missed. In the recent years, after the earthquake in China, the damage The reason for the very big sex is also related to this aspect. Therefore, we must actively explore, deepen the practice so as to accumulate relevant experience, so after in-depth discussions, the possibility of problem solving will be increased accordingly. The related problems of exploration and appraisal of concealed active faults in cities are studied from two aspects.
