结合工程实例,通过位移-时间过程线、位移-孔深关系曲线以及变形速率图,从时间和空间的角度分析监测成果,并将不同部位仪器的监测成果加以对照,综合分析坡体的变形特征。一般情况下开挖坡体的变形量是随着高程的降低而增大,对于存在软岩夹层的岩石边坡在开挖时坡体的变形会表现出与一般情况下不同的特征。实际工程中影响岩体变形的因素是多种多样的,需借助地质资料并结合现场施工进度以及巡视结果分析监测成果,掌握坡体变形特征,从而对坡体的稳定状况做出判断。
Based on engineering practice, the displacement-time, displacement-depth and deformation-speed curves are adopted to analyze monitoring results from points in time and space. In order to obtain a comprehensive analysis of the slope deformation, the monitoring results of instruments installed in different places are compared. Generally speaking, the character of excavating slope deformation becomes larger with the decrease of the altitude. However, the character of deformation of soft rock is different. In fact, the impacting factors of deformation are various in practical projects; therefore, it is necessary to understand deformation mechanism under various factors by means of geological information combining with construction progress and patrol result in order to estimate the stability state of slope.
