Method and system for predicting consolidation of soft soil reinforced with horizontal-vertical grid drainage boards
By establishing a cylindrical calculation model and dividing it into unit cells, and comprehensively considering multiple factors, the consolidation process of soft soil reinforced by horizontal-vertical grid drainage boards is predicted. This solves the problem of the lack of prediction methods in existing technologies and achieves high-precision prediction of the consolidation process.

Abstract
本发明提供一种水平‑竖向网格式排水板加固软土的固结预测方法及系统，涉及环境岩土工程领域，该方法包括以下步骤：将圆柱状计算模型沿径向、轴向，划分为设定数目的单元体，设定参数与模型边界条件；计算所有单元的总应力、有效应力和渗透系数，计算相邻单元及边界的等效渗透系数和水力梯度；计算轴向与径向两个方向相邻单元体间及边界位置的渗流通量；根据单元体初始体积、渗流通量，确定适用所有单元体的时间增量值；根据渗流通量、时间增量，计算每个单元体的体积变化量和新体积值，计算模型平均沉降量。本发明综合考虑水平‑竖向网格式排水板、分阶段吹填、非线性土体本构关系，能准确预测水平‑竖向网格式排水板加固泥浆的过程。
