摘　　要：针对隧道围岩变形位移的监测中普遍存在着不能有效地剔除监测位移中的虚假噪声以及监测点不能完全紧跟掌子面步设致使隧道开挖后部分重要的前期位移释放值丢失2个典型难题,提出了基于奇异值分解和免疫克隆BP网络的隧道围岩变形位移的前推修正模型。实例表明该模型对隧道围岩监测位移信息进行的降噪处理和前推修正能取得很好的效果,可为评判隧道围岩的稳定状态提供真实可靠的数据资料。Aimming at the two ubiquitous,typical and difficult problems about the false noise of monitoring displacement can＇t be rejected effectively and partial important preliminary displacement values may be lost for the reason that monitoring points can＇t be installed with the pushing of tunnel face in monitoring displacement of tunnel surrounding rock,the model of deducing onwards and revising displacement of tunnel surrounding rock based on singular value decomposition and immune clone BP network is put forward.The result of instance indicates that de-noising,deducing onwards and revising monitoring displacements of tunnel surrounding rock by this model can reach a good effect.The model can provide real and reliable data for judging the stability of tunnel surrounding rock.
