摘要
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。
On the basis of the mechanics analysis of high water material solidifying backfill body (abbr. HW body) in the condition of self-supporting, the strength designing formula of self-supporting HW body, which is called High Water Model, is developed. The influence of the HW body's exposure length has been considered in the new model. That is the essential difference between the new model and the formers. The factors that influence the HW body's strength designing, like internal friction angle, height, length and width, have been analyzed. Using the new model, the industrial experiment result has been analyzed in Canada and the High Water Model has been proved.
