中文摘要：
在地下工程注浆治理中,不同类型的浆液与水具有不同的相界面特征,浆–水相界面特征对揭示注浆堵水机制及建立浆–水混合区数值模型具有重要意义。通过分析不同浆液的浆–水相界面形态,得到注浆材料相界面表征方法和适用类型;通过注浆模拟试验,开展水泥水玻璃浆–水相界面测定试验,得到动水条件下水泥水玻璃浆–水相界面特征;对试验数据进行回归分析,将相函数拆分为高度函数和宽度函数对相界面几何特征进行描述,并分析浆–水相界面特征的影响因素。研究成果对注浆堵水机制的发展和浆–水界面数值模型的建立具有一定的参考价值。
英文摘要：
In underground grouting engineering, phase interfaces in different types of grouts and water have different characteristics; the characteristics of slurry-water phase interface have great significance to describe the mechanism of grouting for stopping up water and build a numerical model of slurry mixing zone. By analyzing the phase interface morphologies of different slurries, the characterization methods and application types are obtained. By the laboratory experiments, determination test of cement-silicate mixed area is carried out; and characterization of cement-silicate grout phase interface in dynamic water is obtained. By analyzing the experimental data, phase function is decomposed into height function and width function in order to describe the geometric features; besides, the influencing factors are analyzed. The results will be helpful to develop the mechanism of grout and block water as well as establish the numerical model of slurry-water interface.
