深基坑围护结构的动态稳定性数学分析

深基坑围护结构的稳定性在基坑开挖到一定深度后显得更为重要，而在这以前，开挖已积累了一定的监测数据，如何利用已积累的数据，分析和预报基坑在以后开挖工况中的稳定性成为研究的重点．为此，本基于非线性系统动态稳定性分析理论，建立了基坑在开挖施工过程中所服从的数学模型，利用建立的模型，分析了基坑围护结构的动态稳定性。

The Dynamic Stability Mathematics Analysis of Retaining Structure in Deep Excavation Engineering

The stability of retaining structure is very important when the depth of excavation is coming to base bottom. Much more monitoring data have been obtained before it. To engineers, how to use these data to analyze and predicate the stability of retaining structure in next steps is a key problem. In this paper, based on the nonlinear theory of system dynamic stability, mathematics model that retaining structure obeys is established, and then use this model to analyze dynamic stability of retaining structure. The study shows that mathematics model based on monitoring data can be more suitable for practice engineering.
