工程实践表明,在边坡、地基或地下工程岩体中几组地质结构面和临空面的组合往往构成可能失稳的岩石结构体、存在向临空面运动的可能性、影响到工程岩体的稳定性。这时必须针对这种可能失稳的结构体进行分析,采取必要的加固或处理。关于岩石结构体的稳定分析,文献中已有一些报导,但偏重于图解和计算方法、一般是针对特定单一块体的解析,仅应用于边坡工程。采用矢量解析原理、利用电子计算机无 Engineering practice shows that the combination of several sets of geological structure faces and temporary faces in rock slopes, foundations or underground engineering structures often constitute rock structures that may be unstable and have the possibility of moving to the apron surface, affecting the engineering rock Body stability. At this time must be against the structure may be instability analysis, to take the necessary reinforcement or handling. There have been some reports in the literature about the stability analysis of rock structures. However, emphasis is placed on the methods of illustration and calculation, which are generally applied to the analysis of a single block and applied only to slope engineering. Using vector analysis principle, the use of electronic computers without
