摘要
探明驳岸基础对于城市地下空间的开发利用具有重要意义。根据驳岸基础与下部土层的波速差异,在驳岸上布置测线,可采用瑞雷面波探测驳岸基础深度。选用人工锤击震源、合适的偏移距及道间距,采集数据经过CCSWS系统的处理分析,得出地下波速剖面图,可确定驳岸基础的埋深。本文说明了瑞雷面波在探测驳岸基础中应用的可行性。
It is important to figure out the revetment foundation, for the city underground space development. Depending on the velocity difference of revetment foundation and the surround soil, the rayleigh wave method was used to detect the revetment foundation depth. The data with artificial hammer source, appropriate offset and channel distance were collected, which were processed and analyzed with CCSWS system. The velocity profile was obtained, and the depth of the revetment foundation was determined. The feasibility of rayleigh wave method was feasible in detecting revetment foundation.
