Abstract

Abstract: The City of Tangshan is a typical urban city underlain by the karst terrain and the Tangshan Times Square is at the center of the city. The development of the karst rock has a significant impact on the proposed construction near this area. The development of the karst bedrock, site stability and its evaluation, karst rock stability evaluation as well as the karst rock mitigation aspects are presented based on the site investigation data. Among these aspects, the mitigation of the karst rock, horizontal and vertical grouting limits, grouting materials and their QA/QC procedures have been verified by the applications in the actual construction projects.

Key words: Covered Karst, Karst Development and Evaluation, Stability Evaluation, Karst Rock Mitigation, Grouting
