摘要
为了解水布垭河床覆盖层经强夯处理后的沉降变形及处理效果,通过建立G(1,1)灰色预测模型,编写计算程序,分析其沉降变形规律和沉降机理,对河床保留覆盖层的沉降进行预测分析。结果表明,G(1,1)灰色模型比较适合短序列观测资料的分析和预测,预测精度较高;同时也说明水布垭河床覆盖层经强夯处理后效果较好,处理方案可行且经济合理。
To understand the displacement transformation of Shuibuya dam riverbed after overlays being pounded strongly and the disposal effect, this paper makes a G （ 1,1 ） model to forecast the displacements of reserved overlays of riverbed of Shuibuya dam by writing programs and analyzing the riverbed＇s transformation law and displacement mechanism. The computed results show： the gray forecast model is fit well in the analyzing and forecasting short serial data and rather high precision; at the same time, it can show the pounding effect well and reasonablenesess in economy.
