摘　　要：在城市工程建设施工中,有很多建设项目的地块需要进行回填区填料的密实度检测,以最近兴起的多道瞬态瑞雷面波法在贵州省安顺市尔盛新材料项目地块进行面波检测为例,对瞬态面波的仪器设备、工作原理、野外布置方式,资料解释和应用效果等进行了阐述。在应用效果很接近真实的情况下,得出瑞雷波在垂向激震产生的波组中能量最强而易于识别、对场地的要求不高、有一定的穿透能力且浅层分辨率高等优点。提出了瞬态面波检测可以用来评价回填区填料密实度,为工程施工质量及回填区进行浅层平板荷载试验选点提供参考。In urban engineering construction,there are many construction projects that require compactness testing of fill materials in the backfill area.This article takes the recently emerged multi-channel transient Rayleigh surface wave method as an example for surface wave detection in the Ersheng New Materials Project site in Anshun City,Guizhou Province,Explained the instrument equipment,working principle,field layout,data interpretation,and application effects of transient surface waves.In cases where the application effect is very close to reality,it can be concluded that Rayleigh waves have the strongest energy in the wave group generated by vertical excitation,are easy to identify,have low requirements for the site,have certain penetration ability,and high shallow resolution.Transient surface wave detection has been proposed to evaluate the compactness of backfill materials in the backfill area,provide reference for engineering construction quality and Selection of shallow plate load test points in the backfill area.
