瞬态瑞雷波在预应力管桩施工中的应用

Application of Transient state Rayleigh wave in pre-stressed steel pipe construction

本文通过在福建省闽侯县上街镇某项目中的开展物探勘探-瑞雷面波勘探,结合已有钻探成果,形成连续的地质剖面,更准确地揭示场地岩土层、查明埋藏地下的孤石、岩核等不良地质体,为预应力管桩桩基施工时避开不利的埋藏物、合理配置桩长提供依据,减少浪费,节约成本,在沿海地区火成岩区具有一定的推广价值。

Through a geophysical prospecting with Rayleigh wave in a project at Shangjie Town,Minhou County in Fujian Province,combined with the existing drilling achievement,continuous geological profile was formed to disclose the location ground level,to verify bad geologic body accurately such as buried underground boulder and crag nucleus and so on,for avoiding of disadvantageous buries and arrangement of pile length reasonably in driving of pre-stressed pipe pile leading to reducing the waste and saving the cost.It has certain promoting value in the coastal area.
