本文讨论了裘布衣稳定流理论应用在基坑降水计算中存在的问题,包括假设的稳定流和实际的非稳定流问题,假设平缓的水力梯度与实际的大降深问题,影响半径的逻辑矛盾问题,弱透水层的阻隔和渗出面问题,数值法计算问题等。裘布衣稳定流理论简单,局限性也很明显,计算者务必十分注意实际情况与理论假设之间的差别及其带来的后果,慎重使用。
In this paper, we discuss the problems existing in the calculation of foundation pit dewatering, including the hypothesis of steady flow and actual unsteady flow, the hypothesis of gentle hydraulic gradient and actual deep drop, the logical conflict of influence radius Problems, impermeability and seepage of the aquitard, and numerical problems. The theory of the stability of the fur coat is simple and the limitation is also very obvious. The calculator must pay great attention to the difference between the actual situation and the theoretical assumption and the consequences, and should be used with caution.
