在建筑工程场地中,常常遇到人防地道、软弱层等不良地质体,对建筑物的安全造成威胁,而准确查明该类隐患,并采取相应的处理措施,是建筑工程中面临的较为普遍的问题。本文简要叙述了高密度地震映像法的基本原理和方法技术,并通过工程实例介绍了建筑场地中隐伏地道、松散夹层、湿陷性黄土等几种不良地质体的地震映像特征,并与开挖验证结果进行了对比分析,充分证明了高密度地震映像技术在建筑工程场地勘察中具有良好的应用效果。
In the construction site, often encounter civil defense tunnels, weak layers and other adverse geological body, pose a threat to the safety of buildings, and accurately identify the hidden dangers and take appropriate measures to deal with, is more common in construction projects The problem. In this paper, the basic principle and method of high-density seismic mapping method are briefly described. The seismic mapping features of some unacceptable geological bodies such as hidden tunnels, loose sand sheets and collapsible loess in construction sites are introduced through engineering examples. The results of the verification are compared and analyzed, which fully proves that the high-density seismic mapping technology has a good application effect in the construction site investigation.
