摘要
查明地基岩土体结构是岩土工程勘察的一项重要内容,对地层中存在的不良地质结构勘察的准确性直接影响到加固和设计方案的选择。通过引进、介绍多道瞬态瑞雷面波勘察的原理和方法,本文以一城建地基岩土结构勘察工程为例,开展了多道瞬态瑞雷面波勘探工作。根据瞬态瑞雷面波勘探结果和少量钻孔资料,对场地内存在松散层和空洞等不良地质结构体的分布进行了识别。在数据处理和分析中,瑞雷面波勘探结果与工程钻探数据相结合,提高了面波反演解释的准确性,达到综合勘探的效果,最终解释地层松散层、空洞结构异常10处,其中有6处为钻探工程所验证,研究结果为地基处理方案的设计提供了重要依据。
Identify the geotechnical structure of foundation is one of most important works in geotechnical engineering investigation. The prospection accuracy of the unfavorable geotechnical structure of foundation will directly affect the selection of the strengthening and designing scheme. By introducing the mechanism and method of the multi-channel transient Rayleigh wave technique, this paper put forward a case study of prospecting the geotechnical structure of a municipal foundation. According to the Rayleigh wave test results and a few borehole data, the distribution of the unfavorable geotechnical structures were found out accurately. To achieve an integrated exploration, the accuracy of the inverse interpretation was greatly improved through the combination of the transient Rayleigh wave technique and drilling technology. Finally, 10 unfavorable geotechnical structures were interpreted and 6 were verified by drilling engineering. The study results will provide an important basis for the designing of the foundation treatment scheme.
