烟台万达广场桩基工程遇溶洞、裂隙及破碎带综合处理技术

Comprehensive Treatment Technology of Cave,Fracture and Fracture Zone in Pile Foundation of Yantai Wanda Plaza

烟台万达广场塔A4楼桩基工程施工时遇到溶洞、裂隙及破碎带等不良地质,为收集详细的地质信息,首次利用超前钻钻探技术"一桩一探"结合跨孔弹性波CT技术,不但探明桩身及桩身以下一定范围内的地质情况还收集了整个场地内不良地质的空间分布、形态及连通性。

The A4 tower pile foundation engineering constructing ofYantai wanda plaza was in unfavorable geological conditions, such as karst cave, crack and fracture zone. To collect detailed geological information, we used advance boreholes technology combine with elastic wave CT technology successfully gathered a certain range of geological information beside pile body and bad geological spatial distribution, shape and cormectivitythroughout the whole filed.
