由于局部地区边界条件、岩石力学性质或其它因素的改变和变化,当构造应力活动时,将引起局部应力场的出现。这些现象在构造模拟实验中经常可见,在力学理论上也认识一致,但在地质构造领域中实测和探讨局部地应力场的问题,国内则很少研究。我们这次在煤岭弧形断裂附近实测和研究局部地应力场,是结合北京市地震地质会战工作需要而进行探索性工作的,并以期将来更好地为工程建设和找矿服务。在这次工作中得到陈庆宣先生的热情指导和帮助,在此表示谢意。
Due to the changes and changes in boundary conditions, rock mechanics properties or other factors in local areas, the local stress field will be induced when tectonic stress is constructed. These phenomena are often seen in structural simulation experiments and are also recognized in mechanics theory. However, there are few studies on the measurement and exploration of local stress field in the field of geological structure. This time, we measured and studied the local stress field near the arc-shaped fault at Coal Mine, and conducted exploratory work in connection with the needs of the earthquake and geological battle in Beijing. In the future, we will better serve engineering construction and ore prospecting. Thanks for the warm guidance and help from Mr. Chen Qingxuan in this work.
