面波勘探在工程勘察中的应用
|
摘要
面波勘探作为一种地球物理勘探方法,具有方便、快捷、经济、分辨率高、抗干扰能力强等特点。面波勘探可分为两大类:天然源面波勘探与人工源面波勘探。人工源面波法对浅部地层分辨率较高,但受激发能量限制勘探深度有限,微动勘探深度大,但浅部存有勘探盲区,采用瞬态面波法与微动联合勘探,可以兼顾浅层分辨率和探测深度。本文介绍了面波勘探的原理、野外装置。本文分别介绍了人工源面波勘探、天然源面波勘探在岩溶勘察中的应用及人工源与天然源面波联合勘探在地层划分中的应用实例,充分说明了面波勘探在工程勘察中的有效性。
As a geophysical exploration method, surface wave exploration has the characteristics of convenience,rapidity, economy, high resolution and strong anti-interference ability. Surface wave exploration can be divided into two categories: natural source surface wave exploration and artificial source surface wave exploration.Artificial source surface wave method has high resolution in shallow strata, but limited exploration depth due to excitation energy limitation and large micro-motion exploration depth. However, there are blind exploration areas in shallow strata. The combination of transient surface wave method and micro-motion exploration can give consideration to both shallow resolution and exploration depth. This paper introduces the principle and field equipment of surface wave exploration. In this paper, the application of artificial source surface wave exploration and natural source surface wave exploration in Karst Exploration and the application of combined exploration of artificial source and natural source surface wave in stratum division are introduced respectively, which fully illustrates the effectiveness of surface wave exploration in engineering exploration.
