文中在保证地层内具有稳定流动的基础上，利用保角变换对顶底不渗透油藏中心有一口水平井的产量公式进行了重新推导，给出了水平井产量公式的修正公式，并且利用等值渗流阻力法进行了解

By the law of conservation of mass and the principle of effective stress as well as the equilibrium differential equation, an anisotropic coupled model for the analysis of groundwater seepage and stress is developed.

根据质量守恒定律、有效应力原理、以及土的平衡微分方程建立了各向异性渗流场与应力场的耦合分析的数学模型。

Damage of permeability deformation has been studied contentiously since Dongpinghu reservoir dam had been built.

东平湖水库围坝自建成以来，对渗流破坏坝基土的研究即持续不断，但由于工程设计的目的和研究单位出发点的不同，侧重点各异。

Based on the summation of numerical solutions of the free water surface seepage flow, a new concept called Regional Identification Function is put forward. It is pointed out that the reason why the initial flow method is unstable is that the RIF is discontinuous. Linearization continuity method for the RIF is suggested and then a revised initial flow method is presented.
