摘　　要：随工程建设不断发展,开始大量涌现越来越多的深基坑与超深基坑,同时也带来许多亟需解决的工程难题,其中深基坑开挖对周边环境的变形影响分析尤为重要,从具体工程实例入手,根据深基坑开挖的前、中、后不同阶段的全过程管理与监测数据为依托,采取多专业(勘察、设计、监测)联合方式,借用不同数值分析方法对影响结果进行分析比较,进而反演推算合适参数及计算模型,通过不断对实际情况进行验证,从而对类似工程更好预测分析效果,为工程实际应用创造更大的价值。With the continuous development of engineering construction,more and more deep foundation pits and even ultra-deep foundation pits have begun to emerge in large numbers.At the same time,it also brings many engineering problems that need to be solved urgently.Among them,the analysis of the impact of deep foundation excavation on the surrounding environment deformation.It is particularly important.This article starts with specific engineering examples.Based on the entire process management and monitoring data of different stages of excavation of the deep foundation excavation,it adopts a multi-professional(survey,design,and monitoring)joint method to borrow different.The numerical analysis method analyzes and compares the impact results,and then inverses and calculates the appropriate parameters and calculation models.Through continuous verification of the actual situation,it achieves better prediction and analysis results for similar projects and creates greater value for practical application of the project.
