铜陵市小街塌陷区工程物探的应用

An Engineering Geophysical Application in Depression Disaster Area, Tongling, Anhui

以铜陵市小街塌陷区为例,阐述了城市塌陷灾区运用以浅层地震勘探为主的综合物探方法,在查明第四系厚度、隐伏断裂破碎带、隐伏洞穴和划分塌陷区边界等方面的应用效果.

Taking the Xiaojie depression urban ctea of the City Tongling, Anhui Provinee as an example, it is certain that comprchensive geophysical methcde, particularly sha low seismic explcration, are effective for depression area investigation by determining the thickness of the Quaternary system, locating the pesitions of the buried fault-fractured zenes and ccllapsed caves, and delineating the boundary of the depression area. In this paper a brief case history of the depression disaster area investigation is given.
