通过将现场信息采集、优化反演参数及围护结构变形和稳定分析有机地进行结合，对基坑支护位移和安全性监测建立了动态预报技术，包括提出了分析理论和方法。其基本过程是：第一步，采集现场量测信息；第二步，借助优化反演过程获得计算参数；第三步，用反演计算得到的参数预测下一步开挖的位移量及稳定性。这一方法可在基坑开挖过程中，依据现场量测信息，对基坑开挖的安全性及时作出预测和评估，从而指导施工。
By combining the on-site information collection, optimized inversion parameters, and deformation and stability analysis of the envelope structure, a dynamic forecasting technique was established for monitoring the displacement and safety of foundation pit support, including the analysis theory and method. The basic process is: the first step is to collect the site measurement information; the second step is to obtain the calculation parameters through the optimization inversion process; the third step is to use the parameters obtained by the inversion calculation to predict the displacement and stability of the next excavation. . This method can predict and evaluate the safety of foundation pit excavation in the process of foundation pit excavation, based on the site measurement information, so as to guide the construction.
