锚固灌浆过程中及工后交河故城崖体的变形特征研究

 依托国内最大的土遗址加固工程——交河故城抢险加固工程，根据崖体破坏的特点，采用南瑞大坝全自动监测仪器连续高精度监测锚固灌浆过程中崖体的变形。通过监测数据的分析，发现灌浆对崖体扰动最大，锚固对崖体扰动较小，加固前后崖体的变形曲线特征对比证明锚固灌浆取得了成功的加固效果。研究结论为交河故城的整体科学保护提供依据，为类似土遗址加固工程锚固灌浆研究提供参考。

RESEARCH ON CLIFF DEFORMATION FEATURE OF JIAOHE RUINS DURING AND AFTER ANCHORING AND GROUTING

Based on the largest earthen architecture conservation engineering，Jiaohe ruins rescuing conservation engineering，and the particularity of the cliffs，Nanrui dam automatic monitoring instrument is applied to survey the deformation of cliffs during anchoring and grouting. Analysis of the monitoring of the cliff proves grouting disturbs the cliffs more intensely than anchoring. The deformation characteristics of the cliffs before and after the conservation illustrate the successful conservation of anchoring and grouting. The conclusion provides the foundation for entire scientific conservation of Jiaohe ruins；furthermore，it gives the reference to the research on the anchoring and grouting of similar earthen architectures.
