高密度电阻率法在平阴县岩溶地质灾害调查中的应用

Application of High Density Resistivity Method in Investigation of Karst Geological Hazards in Pingyin County

摘要:

平阴县地处泰山山脉西延余脉与鲁西平原的过渡地带，地势南高北低，中部隆起，属浅切割构造剥蚀低山丘陵区。其县城及周边岩溶较发育，给当地居民住宅及生产生活造成一定影响。为查明岩溶地质灾害塌陷等造成的不良影响，利用高密度电阻率法圈定地下岩溶、溶洞等不良地质体的分布范围及第四系的大致厚度，应用效果较好。

Abstract:

Pingyin county located in the transition zone between the western offshoot of Taishan Mountain and the plain of western Shandong province. It is high in the southern part and low in the northern part. It belongs to the weathered hilly and mountainous region with a shallow cut structure. Karst is well developed in and around the county, which may have certain influence to local living houses and production. In order to find bad effects caused by collapse and other geological hazards, the distribution of underground karst, solution cavity, other bad geological bodies and approximate thickness of the Quaternary system in this area have been investigated by using high density resistivity method. This method can gain a good application effect.
