摘要
介绍了地震层析成像技术的原理及其在深圳龙岗志联佳大厦建筑场地岩溶勘察中的 应用.采用井间透射层析方法,详细划分出基岩顶面界线和基岩内的溶洞、溶蚀带等不良地 质体,从而为大厦的建筑设计提供了准确的桩位和桩基参数。
The paper describes the principle of technique of seismic computerized tomography and it's application to reconnaissance of karst in the building ground of Zhilianjia mansion in Longgang district, Shenzhen. Transmission computerized tomnography among walls is used to map the surface of bedrock and the abnormal part such as karst caves and corrosion zones. As a result, the parameters of founda- tion pile and it's location can he accurately determined for architectural design.
