深基坑工程普遍存在于城市建设过程中,研究深基坑施工过程中的环境效应是防灾减灾工作的重要组成部分.高质量地利用监测数据,并结合人工智能技术分析和预测深基坑施工过程中周边环境的变化具有重要的意义.依托某顶管工程项目,分析了始发井基坑开挖施工对周边环境的影响,同时将重要监测参数形成时间序列,进一步利用高级循环神经网络LSTM实现监测参数的超前预测.结果表明:各个监测变量之间呈现出联动规律,但是由于监测数据数量太少或者施工偶然因素影响,监测变量的联动性相对较弱,循环神经网络预测不理想.这些工作对于提高基坑预警理论具有一定的前瞻意义.
Study on the Time Series Linkage Law of the Construction Monitoring of Pipe Jacking Foundation Pit
Deep foundation pit engineering widely exists in the process of urban construction.It is an important part of disaster prevention and mitigation to analyze the monitoring data and study the environmental effects in the process of deep foundation pit construction.It is of great significance to analyze and predict the changes of the surrounding environment during the con-struction of deep foundation pit by using the monitoring data with high quality and combining the artificial intelligence technolo-gy.Relying on the pipe jacking project,this paper analyzes the impact of the excavation of the foundation pit of the starting shaft on the surrounding environment.The important monitoring parameters are processed into a time series,and advanced cy-clic neural network(LSTM)is employed to achieve the advance prediction of monitoring parameters.The results show that there is a linkage law among the monitoring variables,but the linkage of the monitoring variables is relatively weak due to the lack of monitoring data or the impact of construction accidents,and the prediction of the cyclic neural network is not ideal.These works are of forward-looking significance for improving the early warning theory of foundation pit.
