水工大体积混凝土工程多数都存在的一些施工缺陷（如裂缝或内部灌浆缺陷），改变了正常的设计工作条件。针对这个问题，提出了模拟接缝灌浆缺陷的模型和约束条件超过未知量的解法。解法的计算具有累积应力功能。用此解法，探索某合缺陷高拱坝的运行工作状况，得到和实测相近的变形以及内部应力重分布状况，为工程设计提供补强依据。
Some of the construction defects (such as cracks or internal grouting defects) that exist in most of the hydraulic mass concrete works change the normal design working conditions. In response to this problem, a model to simulate the joint grouting defects and a solution to the problem that the constraint exceeds the unknowns are proposed. Calculation of the solution has a cumulative stress function. With this solution, the operational status of a high-arch dam with a certain defect is explored, and the deformation and internal stress redistribution similar to the measured value are obtained, which can provide reinforcement basis for engineering design.
