本文从分析自立状态下高水固结充填体的受力情况入手，推导出了高水固结充填体自立的强度计算公式──高水模型，该模型考虑了暴露长度对充填体自立强度的影响，这是它与其它模型在本质上的不同之处．着重分析了影响充填体强度计算的内摩擦角、高度、长度和宽度等因素。结合加拿大的工业性试验情况进行了实例分析，从而验证了模型的合理性。 Based on the analysis of the stress conditions of self-standing high-water consolidation packing, this paper deduces the self-standing strength formula of high water consolidation packing ─ ─ high water model. The model considers the influence of exposure length on self-standing strength of filling body Impact, which is essentially different from other models. Focuses on factors such as internal friction angle, height, length and width that affect the calculation of filling strength are analyzed. The case analysis of industrial experiments in Canada was conducted to verify the rationality of the model.
