| description | High density polyethylene(HDPE) material is excellent, often made into bellows, and is an important part of the urban drainage system. The blasting seismic dynamic load is one of the key problems affecting the safety of buried pipeline structures. As a commonly used artificial source excitation method, blasting is often used to study the seismic structural response test. Combined with the characteristics of the buried typical stratum of pipelines in urban areas, full-scale blasting tests of embedded HDPE bellows are conducted. The characteristics of vibration acceleration and strain in the empty pipe under blasting vibration are monitored and analyzed. LS-DYNA is used to establish the model based on the field test conditions and verify the rationality of the model. Then, the models of different water levels are added and the dynamic response characteristics of the pipeline are calculated and analyzed. Finally, according to the max allowable stress criterion, the safety of the pipeline is evaluated. |
