灰色系统理论在高填石路堤工后沉降预测中的应用

Gray system theory in the high embankment filling Settlement Forecast

中文摘要英文摘要

高填石路堤竣工后,在很长一段时间内,将持续不断地发生沉降变形,因此准确预测路堤的沉降量,对道路工程的设计和施工极其重要,但目前尚无能够全面反映各种情况的理论公式和数值方法。由于灰色系统理论可利用原始资料建立动态预测模型,并能达到较高的预测精度,以“沪蓉西高速公路高填石路堤”为工程依托,运用灰色系统理论中的GM(1,1)预测模型对各测点进行沉降预测,通过与路堤沉降的实测数据的误差分析进行精度检验,结果表明:预测计算值与实测值平均相对误差小于0.01,精度等级为一级,符合精度要求。

High-filling after the completion of the embankment in a long time, the ongoing settlement took place, so an accurate prediction of embankment settlement, the road works on the design and construction is extremely important, but are not fully reflect the The case theory and numerical formula method. As the gray system theory can be used raw data to establish the dynamic model, and to achieve higher forecast accuracy, “Shanghai-Chengdu Expressway West High Rock Embankment” for the project based on the use of gray system theory in the GM (1,1) Prediction model of the measuring point for prediction of settlement by settlement of the embankment with the measured data for the analysis of the accuracy of testing error, the results showed that: projections calculated and measured the average relative error of less than 0.01, to a level of accuracy, precision in line with the requirements.
