提出了在边界上施加边界位移 ,产生纯剪应力的方法 ,并根据 Cauchy- Kowalewsky定理 ,按位移求解平衡微分方程 ,论证了该方法的可行性。该方法简单易用 ,在地应力场反分析及同类工程中均可得到应用。
The method of applying the boundary displacement on the boundary and generating the pure shear stress is proposed. According to Cauchy-Kowalewsky’s theorem, the equilibrium differential equation is solved according to the displacement, and the feasibility of the method is proved. The method is simple and easy to use and can be applied in the field stress field reverse analysis and similar projects.
