| 摘 要： | 为了查明无锡石唐湾地裂缝发育特征、形成机理及发展趋势,投入了多种勘查方法,瞬态面波方法便是其中的一种.利用基波速度参数对40m以浅进行了详细分层,利用高阶波速度参数对深度超过40m以深部分进行分层.发现地裂缝发育带波速度明显降低,存在面波低速带.发现高阶波勘探深度较基波勘探深度大,可达70余米.

| Abstract: | To recognize the development features, formation mechanism and development trend of geofractures in Shitangwan, Wuxi, many reconnaissance methods were used, one of which was transient surface wave method. Fundamental wave velocity parameters were used to make detailed layering for the section from the depth of 40m upward, and higher-order wave velocity parameters for the section of 40m downward. Wave velocity dropped remarkably in the zone where geofractures were developed, and low-wave velocity zone existed. Higherorder wave exploration could reach a depth up to 70m, deeper than the fundamental wave. |
