摘要：

This paper describes the inspection for cavity detection in an urban area in Torrente (Valencia, Spain). A shallow cave was found during the excavation work for a new sewerage project. Digging activities were stopped immediately and a GPR survey (400 MHz antenna) was required to reorganise the sewerage planning. The 3D GPR-mapping pinpointed most of the detected cavities on one side of the street. As a result, the sewerage system layout was moved to the side of the street where less evidence of cavities was detected. Therefore, GPR technique is a helpful tool for minimizing costs, time, work safety risks and inconveniences to people living in the neighbourhood during civil engineering works, especially in urbanised areas.
