瓦房店三家子地区岩溶探测与研究
|
摘要
在辽南瓦房店三家子岩溶发育区进行地震地质调查与工程地质钻探的基础上，布置了ＣＴ层析成像、地质雷达等多种地球物理探测，结果表明，本区断裂构造纵横交错，第四系覆盖层厚度为６～９ｍ，基岩是由寒武系下统的厚层灰岩或泥灰岩组成，岩溶发育，埋深多为１０～３０ｍ，少数为５０～７０ｍ。钻探结果与地球物理探测在岩溶埋深、第四系覆盖层厚度等结果上是吻合的。同时还对岩溶的形成与塌陷因素进行了分析，提出了一些防治措施
On the base of seismic geological surveies and engineering geological drills, CT geotormography and geological radar probing lines are fixed up in the area of Shanjiazi,Wafangdian city of south Liaoning.The probing result shows:in the karst developing area of Sanjiazi,crisscross fault structures are Complicated; the thickness of Quaternary is between 6～9m;rocks are consisted of thicklayer limestone or mud limestone of lower Cambrian;the depth is mainly between 10～30m,seldom between 50～70m. Probes of drilling, have the same result with that of geophysical′s in the aspect of preceding.The forming and subsiding factors of karst are analyzed in this paper, and preventing measures are also given.
