Analysis on Influence of Construction Vibration of Diaphragm Wall for Comprehensive Well of Utility Tunnel on Surrounding Buildings
Taking the H8 comprehensive well of the utility tunnel in the section of Huaguan Road in Tianhe Smart City as a research object,the influence of the construction vibration of the underground diaphragm wall for the comprehensive well of utility tunnel on the surrounding buildings is studied.The geotechnical engineering software MIDAS GTS is used to simulate the influence of the impact rock breaking of the underground diaphragm wall for the comprehensive well of the utility tunnel on the vibration of the pile foundation of the adjacent substation.Through the analysis on the key steps of the construction,the law of the peak vibration velocity of the pile foundation of the substation is summarized,and the safety evaluation is carried out according to the allowable vibration safety standard.The relevant research results play a guiding role in the reasonable selection of construction machinery,construction technology and construction vibration protection measures,which provide the reference for the implementation of similar projects in the future.
