摘要
针对沼泽草甸层地区工程地质特征,以新疆兵团垦区沼泽草甸层试验路段为依托,探讨了该类地区路堤填筑过程中地基沉降发展规律,并通过对比分析经验法沉降预测模型,给出了适合沼泽草甸层地基的沉降预测模型。最后,以预测沉降曲线与实际监测值对比,结果表明,双曲线法预测效果较好,适用于该类地区路堤填筑时沉降预测。
With regard to the construction area in geological feature of swamp meadow,this text discusses the regulation of foundation subsidence during filling the embankment in such area,relying on the testing section of swamp meadow in the reclamation area of Xinjiang corps. Besides,it provides the forecast model of subsidence applicable to the subsidence of foundation with swamp meadow,by means of practicing the subsidence with forecast model through comparing and analyzing experiences. Finally,the comparison of the forecast subsidence curve with the actual value observed,the results indicated the conclusions that the hyperbola method has a better effect,which is applicable to be used in the subsidence forecast for such area in embankment filling.
