基于时间序列的深基坑支护结构变形预测

基坑工程由于受多种因素的影响．目前已成为岩土工程中的重点和难点。在基坑施工过程中，需要根据现场的实际工程地质条件及选择的支护型式、建筑物的安全等级．对支护结构的变形进行严格控制。时间序列分析主要是指采用参数模型对所观测到的有序的随机数据进行分析与处理的一种数据处理方法。通过现场量测的深基坑围护结构变形信息资料，对数据进行整理和分析．利用时间序列分析法对支护结构的变形作出预测，以保证基坑安全施工。

Deformation Forecasting for Supporting Structure of Deep Pit Based on Time Series

Foundation pit is affected by some factors and it also is the key problem of geotechnical engineering. In the course of the construction of foundation pit, the deformation of supporting structures must be controlled strictly according to the engineering geological condition, style of the supporting and safety level of the building. Time series analysis is a data processing method that establishes parameter model to process the observation data. Through analyzing the field deformation data of supporting structures, the prediction can be gained by time series model so as to guarantee the safety.
