| 摘 要： | 针对开采地下水这一特定问题,以在抽水实践中地下水水位面是一以井心为顶点的旋转抛物面为出发点,研究了地下水开采过程中岩土体应力变化的时空规律。通过分析影响内部应力变化的宏观物理量—开采影响半径、井心水位下降和空间位置,可以方便的得到随着时间变化岩土体内部应力变化的全程规律。同时,分析了影响边界、下沉位置等因素对计算结果的影响。

| Abstract: | For the special problem of pulling out underground water, on the basis of what underwater level surface is rotating parabola face in the center of well during pulling out underground water, the paper studied time-space laws of rock-earth body stress changes during pulling out underwater. Trough analyzing such macro-parameters as influencing radius, water level drop and space position which affect inner stress changes, it is easy to time-space laws of inner rock-earth body stress changes with time. As the same time, the effect on computation result such as boundary, sinkage location and so on is analyzed. |
