岩土工程注浆技术与其应用研究

注浆技术因其在渗漏、突水突泥等灾害治理及软土加固方面的显著优势,目前在岩土工程项目建设及运营维护中应用非常广泛。从基于裂隙岩体分形几何和模糊RES-云模型的可灌性分析理论、高聚物和微生物菌液注浆新材料、三维模型可视化和虚实耦合计算机技术等方面对坝基注浆技术进行了阐释述评,并考虑浆液扩散模型、黏度时变规律和注浆复合体结构特征等对盾构隧道和海底隧道注浆技术进行了探讨分析,最后对桩基后注浆加固原理和荷载-沉降特性等进行探索总结。注浆技术在岩土工程系列项目建设中的应用,必将全面提升岩土项目的工程质量。

Study on grouting technology and its application in geotechnical engineering

The grouting technology is now widely used in geotechnical engineering projects, such as dams, tunnels and pile foundations, because of its significant advantages in control of hazards such as leakage, water and mud inrush. This paper presents a review on the new grouting materials of polymer and microbial fluid, NURBS BREP fine geological modeling and virtual real coupling computer technology, fractal geometry of fissured rock mass and fuzzy res cloud model grouting theory. Some issues are also addressed such as the grouting technology of shield tunnels and subsea tunnels taking into account the slurry diffusion model, viscosity time-varying law and grouting complex structure characteristics. Finally, the principle of post-grouting reinforcement, settlement analysis and grouting amount calculation are summarized. The wide application of geotechnical grouting technology will aid in enhancing the quality of geotechnical engineering projects in all aspects.
