The article provides a calculation on the influence of formation karst hole, or sinkhole, beneath monolithic foundation slab building. It follows from calculation, that reinforced concrete structures are capable bearing load action and ensuring safe operation structure in conditions eventual designed funnel. Calculation building under consideration for an emergency event soil caving with diamet...

introduction the iran has vast areas of karst landforms due to the relatively high carbonaceous rocks deposited during different geologic eras. karst landforms are noteworthy for investigation from many aspects. the primary importance of these regions is the considerable amount of underground water stored in karst formations. these reserves are favorable, both in quality and quantity, as natura...

This paper employs a case history to describe deployment of new TDR cable and communication technologies to monitor stability. It involves remotely monitoring possible sinkhole-induced deformation near a “land bridge” installed over a recent subsidence event. A TDR cable was installed horizontally along with more typical vertical cables to detect possible subsidence induced shearing. In additio...
