摘要：在地下结构的施工过程中，水泥浆能渗透进入粗粒土中，形成一个水泥渗透区域。当这个区域的强度增长很大时，它可以作为结构单元的一部分。然而由于水泥浆渗透机制有许多不确定性以及目前的研究还很不充分，将这一影响应用与实际工程比较困难。本文给出了水泥渗透机制相关的理论，并根据相关的理论可以得到预测水泥渗透深度的试验方程。进一步设计了一个原型试验设备来模拟水泥渗透过程，并使用选择的变量进行了试验设计。利用试验数据进行数理统计确定了影响水泥渗透的主要因素，最后得到一个预测渗透深度的回归模型。研究表明，粗粒土中水泥可以渗透，也可以预测渗透深度，渗透区域可以作为一个结构单元。

Abstract: During construction of underground structure, cement slurry can be infiltrated into a coarse-grained soil and forms a cement infiltrated zone. This zone may serve as a part of structural element when the strength of this zone increases significantly. However, it is not easy to apply this effect in engineering practice due to many uncertainties associated with the infiltration mechanism and lack of researches on this topic. In this paper, the theories related to cement infiltration mechanisms are presented, and an experimental equation which predicts the cement infiltration depth is derived from the existing theories. Further, a prototype laboratory apparatus is devised to simulate the cement infiltration, and an experimental design was performed using the variables selected for the study. With the laboratory data, a statistical analysis was performed to identify the significant factors affecting the cement infiltration, and a regression model was derived to predict the infiltration depth. The study suggests that cement infiltration occur in coarse-grained soil;the infiltration depth can be predicted; and the infiltrated zone may be considered as a structural element.
