With the rapid capacity expansion of urban high-rise buildings and underground space,pit engineering accidents are increasingly frequent.Traditional manual monitoring methods not only have poor timeliness,but also fail to meet the standards in terms of accuracy and authenticity.In contrast,automated monitoring methods continuously provide real-time data and quick feedback,thereby improving the quality of construction and reducing the possibility of accidents.Against this backdrop,this paper has developed a smart pit monitoring system and expounded on its principles,structural composition,and technical characteristics.Through the actual application of the smart monitoring system in a pit engineering project in a certain soft soil area,we analyzed the deep displacement of the soil,water level changes and support axis force changes during the pit excavation process,and finally looked forward to the future development trend of the smart pit monitoring system.The results show that the smart pit monitoring system can collect,transmit,calculate and warn all data of the construction process in real time,effectively making up for the deficiencies of manual monitoring.In the actual application in this soft soil area,the system operates well,successfully identified and dealt with over-limit safety risks of horizontal displacement of two monitoring points and support axis force of three,fully meeting the requirements for safe construction.The research results can provide certain reference value for the application of smart pit monitoring system in similar projects.
