摘　　要：裂隙岩体注浆扩散理论作为注浆理论研究的重要分支,国内外学者已取得了丰硕的成果。关于裂隙岩体注浆理论推导解析解的研究,从抽象的裂隙模型与选用的浆液本构方程两个方面的发展变化进行阐述;关于模型试验,不同学者以单一平板裂隙模型为基础,根据裂隙岩体注浆理论影响因素的不同,对模型试验台的功能与具体型式进行调整;采用数值模拟手段计算裂隙岩体注浆过程,现有的商业软件虽然已能够解决一些问题,但不少学者仍自行编制程序软件,完善计算过程中的裂隙模型与浆液流变性质。针对裂隙岩体注浆扩散理论目前研究进展情况,笔者就裂隙岩体注浆理论的发展,提出了一些见解。As an important branch of the grouting theory study,the grouting diffusion theory of a cracking rock mass had made fruitful achievements by the scholars from home and abroad.As for the study on the grouting theory of the cracking rock mass by the derivation and analytic solution,a statement was conducted on the development variation from two aspects between the abstract cracking model and the selected grout structure equation.As the model test,the different scholars with a single flat cracking model as a base,according to different influence factor of the grouting theory of the cracked rock mass,an adjustment was conducted on the function and certain type of the model test rig.The numerical simulation means was applied to calculate the grouting process of the cracking rock mass.Although the available commercial software could be applied to solve some problems,but many scholars would like to prepare their own program and software to improve the cracking model and rheology properties during the calculation process.According to the present study progress of the grouting diffusion theory,the paper provided some views on the development of the grouting theory of the cracking rock mass.
