膨胀岩体中的湿度应力场理论

Humidity Stress Field Theory in Swelling Rock Mass

软岩工程中的岩体一般为膨胀岩体,受水作用后的应力应变场分析问题十分困难。本文提出了分析膨胀岩体受水作用的湿度应力场理论。重点讨论了建立湿度应力场理论的两大要素:膨胀岩石含水率变化对其力学性质的影响和岩体中湿度变化规律。并给出了湿度应力场理论的控制方程和用该理论分析了简单的平面轴对称问题。

In this paper,the author presents forword a new theory in rock mechanics-the humidity stress field the- ory of swelling rock.Two basic problems,which are change of mechanical properties of swelling rock by ef- fects of water content and the humidity field swelling rock mass,are discussed.Through this stress field theory, the solution of a simple example is given.
