Abstrakt
Kościuszko Mound in Cracow is earthen structure particularly susceptible to deformations, among other things, due to the unfavourable physical and mechanical properties of the ground and a significant tilt of slopes. Since the beginning of its existence to the present day, structural failures were repeatedly occurred, and the biggest took place after 1997, when heavy rains led to the greatest destruction of the entire mound solid ever. Overall renovation, however, did not produced the expected results and did not stop negative atmospheric influences on the monument behaviour. Therefore, in 2012, structural health mo nitoring was installed on-site, providing remote, continuous and automatic measurements of selected physical quantities, which are important from mound technical condition point of view. System is measuring, among other things, changes in vertical displacements, circumferential and radial deformations, ground pore pressure of water within a mound body and humidity of its surface layers. Correlation of results from geodetic, inclinometer and meteorological (derived from the weather station which is part of the monitoring system) measurements will enable a comprehensive assessment of ground layer work mechanisms within the whole mound solid and will be one of the bases for effective strengthening design in the future.
