浅析瞬态面波测试在工程勘察工作中的应用
摘要:瞬态面波测试是岩土工程原位测试方法,其利用一个波长范围内的面波在不同岩土介质中传播过程中产生的频散和速度信息,通过测试软件,合成为反映地层弹性结构特征的面波剖面地层彩色影像图,从而解译地层波速差异。结合塞舌尔某勘察项目,论述了在实际勘察工作中缺乏勘探工作面,简单勘探手段难以查明地层的情况下,采用瞬态面波测试结合部分工程勘探资料,查明地层的工作实例。并根据现场开展瞬态面波测试工作的情况,浅析了瞬态面波测试的优点、局限性等特点。
Abstract:Transient surface wave test is a type of geotechnical engineering field test.It use the dispersion and speed information which produced by the surface wave in one wavelength range spreading in different soil and rock medium.Through the test software,to synthesize as a surface wave section profile color image that reflect the characteristics of stratum elastic structure,in order to interpret the difference in wave velocity.This article takes an Seychelles project as an example to discuss the engineering practice that in the case of being lack of exploration work space,difficult to identify the strata just with simple exploration ways,using the transient surface wave test comparing with engineering exploration data.Meanwhile,the article briefly analyzes the advantages and limitations according to the situation that we using the transient surface wave test on site.
