三峡工程永久船闸高边坡岩体变形监测及变形特征分析

根据三峡工程永久船闸高边坡变形监测成果，对船闸边坡岩体的变形特征及其影响因素进行了分析，永久船闸边坡岩体的变形主要与岩性及地质结构、开挖进程，地应力释放等因素有关。对实测位移与计算位移也进行了比较并对船闸开挖完成后的最终变形进行了预测。最后认为，船闸边坡整体地质条件较好，只要施工得当加上及时支护，其稳定性是能够得到保证的。

Displacement Monitoring and Deformation Characteristic Analysis for Permanent Lock High Slopes of TGP

On the basis of monitoring results obtained from the permanent lock slope of TGP, this paper presents an analysis on the characteristics of rock deformation and its effective factors. The analytic result demonstrates that the rock deformation is mainly related to those factors such as the natures and structures of the rock mass, the excavation progress and the geostress releasing conditions, etc.. In this paper, a comparison between measured deformations and calculated displacements is made and a prediction on the final displacements after the excavation being completed is carried out. Based on these analyses, it is concluded that the stability of the lock slope can be ensured owing to the good overall geologic condition, in case that the construction method is adequate and the slope is supported and lined in time.
