摘要
微动勘探法是近几年逐渐发展起来的勘探方法,是利用仪器采集地球表面各个方向上的微弱震动,是“天然”的信号。从采集的信号中提取面波频散信号,用以推测地下构造。因其高效、无损、适用范围广等优点被广泛应用于能源勘探、工程地质、道路工程、溶洞探测等方面。地下防空洞、隐蔽涵洞等构筑体对城镇建设具有潜在危险,易引起塌陷、透水、沉降等事故。该文选择了典型案例,分析总结了微动勘探方法应用于人防工程探查的应用过程,为解决城镇建设中类似的疑难问题提供了思路和方向。
Micro motion exploration method is a gradually developed exploration method in recent years,which uses instruments to collect weak vibrations in various directions on the Earth's surface and is a“natural”signal.Extract surface wave dispersion signals from collected signals to infer underground structures.Due to its advantages of high efficiency,non-destructive testing,and wide applicability,it is widely used in energy exploration,engineering geology,road engineering,karst cave detection,and other fields.Underground air raid shelters,concealed culverts,and other structures pose potential risks to urban construction and are prone to accidents such as collapse,seepage,and settlement.This article selects typical cases and analyzes and summarizes the application process of micro motion exploration method in civil defense engineering exploration,providing ideas and directions for solving similar difficult problems in urban construction.
