根据覆岩离层注浆减沉的工程实践和理论研究 ,分别就覆岩离层发育规律、注浆减沉机理、地表沉陷预计理论和注浆减沉的适用条件等四个方面 ,提出了 1 8个具体的理论问题 ,其中有些理论问题研究得出了明确结论 ,有些进行了初步探讨或指出研究途径
According to the engineering practice and theoretical research of subsidence grouting by overburden strata, this paper puts forward the following four aspects: the development law of strata stratification, the mechanism of grouting and sinking, the prediction theory of surface subsidence and the applicable conditions of grouting and sinking Some 8 specific theoretical issues, of which some theoretical issues have come to a clear conclusion of the study, some conducted a preliminary study or pointed out that research methods
