土遗址边坡加固不同于一般边坡加固是在于其文物属性。对于高陡濒临倾倒的边坡一般采取＂去头补脚＂的方式进行处理,而对于土遗址边坡须遵从原状保护的原则。土遗址边坡加固后演化过程具有独有的特征。为此,边坡的变形监测资料对分析边坡变形演化规律及边坡稳定性至关重要。采用南瑞大坝全自动变形监测仪对交河故城51-3亚区濒倾边坡加固后的变形进行实时监测,精度达0.01mm。通过对变形数据分析,阐明其变形行为特征,进而挖掘加固后边坡演化过程。研究表明,加固后边坡表现出明显的非线性特征,具体表现为常态稳变和局部突变特性;变形可划分为明显的趋势性变形、周期震荡式变形和随机性变形。研究结论对于类似土遗址边坡加固效果评价具有重要意义。

Conservation of steep earthen slope sites is different from that of common earthen slopes.For high,steep slope in danger of crumbling,the most common treatment is to remove part of the tip and to patch the base.However,an important aim of protecting earthen slopes of cultural heritage interest is to preserve their current appearance,so conservation of such sites poses some special problems.The process of deformation of steep earthen slopes has some unique characteristics.An automatic deformation monitoring instrument with an accuracy of 0.01 mm was installed at the Nanrui dam in the 51-3 sub region of the Jiaohe ruins to gather real-time data on a conserved earthen slope that is in danger of crumbling.Analysis of the data obtained revealed the characteristics of the deformation and the evolutionary process of this deformation.The results indicate that the conserved slope deforms nonlinearly.Parts of the slope change normally and steadily,and other parts deform abnormally and rapidly.Deformation trends could also be observed,namely,periodical vibration deformations and random deformations.The research is of importance for the evaluation of enhancement of similar earthen slope sites.
