The paper deals with joint use of non-invasive monitoring technologies and civil engineering analysis methods aimed at providing multi-sensing information about the structural health of historical and cultural assets. Specifically, linear variable displacement transducers (LVDT) and ground penetrating radar (GPR) are considered for monitoring a significant crack affecting the Consoli Palace in Gubbio, Italy, precisely one of the walls of the cross-hall leading to the Loggia. In this frame, LVDT is adopted to control horizontal amplitude variations of the crack, while GPR is applied to investigate the wall interior and to detect the occurrence of inner issues related to the visible appearance of the crack on the wall surface. The effectiveness of GPR surveys is improved by means of a microwave tomography-based data processing strategy. The main result is that there is a consistency between the monitoring outputs of LVDT, which allowed us to display the crack widening/contraction due to the seasonal temperature variations, and the fact that no significant changes of the geometry of the inner areas of the walls were observed by the GPR.

结合使用探地雷达和裂缝计传感器进行结构监测：在意大利古比奥的历史康索利宫中的应用

本文涉及无创监测技术和土木工程分析方法的联合使用，旨在提供有关历史和文化资产结构健康的多传感信息。具体而言，线性可变位移传感器 (LVDT) 和探地雷达 (GPR) 被考虑用于监测影响意大利古比奥康索利宫的重大裂缝，这正是通往凉廊的交叉大厅的墙壁之一。在该框架中，采用 LVDT 来控制裂缝的水平幅度变化，而 GPR 用于调查墙体内部并检测与墙体表面裂缝的可见外观相关的内部问题的发生。基于微波断层扫描的数据处理策略提高了 GPR 调查的有效性。
