The results show that the chimney will experience multiple \u2018weight loss\u2019 and \u2018overweight\u2019 effects during the sit-down process, inducing compressive stress waves in the chimney. When the sit-down displacement is large, the broken reinforced concrete at the bottom can play a significant buffering effect, and the \u2018overweight\u2019 effect gradually weakens until the sit-down stops. The stress of the inner and outer sides of the chimney wall is obviously different in the process of collapsing and touching the ground. The waveform of the monitoring point of the piezoelectric ceramic sensor is divided into three stages, which specifically characterizes the evolution process of the explosion load and the impact of the chimney. The vibration induced by explosive explosion is mainly high-frequency vibration above 50 Hz, the vibration induced by chimney collapse is mainly low-frequency vibration below 10 Hz, and the vibration characteristics are obviously different. In the process of blasting demolition and collapse of high-rise reinforced concrete chimney, due to the impact of sitting down, the wall of the support tube is subjected to uneven force, resulting in the deviation of the collapse direction. In practical engineering, the control measures of chimney impact, blasting vibration, and collapse touchdown vibration should be fully strengthened to ensure the safety of the protection target around the blasting demolition object.<\/jats:p>","DOI":"10.3390\/s23136240","type":"journal-article","created":{"date-parts":[[2023,7,10]],"date-time":"2023-07-10T01:02:50Z","timestamp":1688950970000},"page":"6240","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Monitoring and Analysis of the Collapse Process in Blasting Demolition of Tall Reinforced Concrete Chimneys"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-4140-4508","authenticated-orcid":false,"given":"Xiaowu","family":"Huang","sequence":"first","affiliation":[{"name":"College of Science, Wuhan University of Science and Technology, Wuhan 430065, China"},{"name":"State Key Laboratory of Precision Blasting, Jianghan University, Wuhan 430056, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianqi","family":"Xie","sequence":"additional","affiliation":[{"name":"College of Science, Wuhan University of Science and Technology, Wuhan 430065, China"},{"name":"State Key Laboratory of Precision Blasting, Jianghan University, Wuhan 430056, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3919-2153","authenticated-orcid":false,"given":"Jinshan","family":"Sun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Precision Blasting, Jianghan University, Wuhan 430056, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongwang","family":"Zhong","sequence":"additional","affiliation":[{"name":"College of Science, Wuhan University of Science and Technology, Wuhan 430065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingkang","family":"Yao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Precision Blasting, Jianghan University, Wuhan 430056, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengwu","family":"Tu","sequence":"additional","affiliation":[{"name":"College of Science, Wuhan University of Science and Technology, Wuhan 430065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,7]]},"reference":[{"key":"ref_1","unstructured":"Chu, H., Xu, P., and Ye, H.
