分析初始地应力场的位移函数法

岩体初始地应力的确定是地下洞室、边坡等岩土工程设计和施工的必要条件。笔者从实用的角度出发,提出了一种将位移函数法和有限元法相结合来模拟初始地应力场的分析方法。实例应用的结果表明:该方法能很好地模拟岩体的初始地应力场,并能为后续开挖过程的有限元分析提供一种与初始地应力场等效且方便的加荷途径,具有良好的实用性。

Displacement function method for analyzing initial earth stress

Confirming initial earth stress of rocks is necessary to design and construct geotechanical engineering such as underground cave and slope. An approach analyzing initial earth stress is presented. That is by means of combining displacement function method and FEM to simulate initial stress field. The result of example indicates that this method can simulate the initial stress field; and offer an equivalent method how to apply load on model for FEM analysis later. Therefore, this method has good practicability.
