With the increasing need for groundwater supplies, there is an urgent need for devising strategies for protecting the precious groundwater resources from contamination. Environmental containment through the use of colloidal silica (CS) based chemical grout is becoming an important step in groundwater protection. CS gels have also been used for geotechnical applications and enhanced oil recovery operations during secondary recovery of petroleum. While there have been some efforts in this vital area, there has not been any concerted effort to understand the processes related to flow and transport of these gelling solutions through porous media. Hence there is an urgent need for a research program to develop our understanding of the processes occurring during chemical grouting through both experimental and numerical investigations in an effort to advance our knowledge towards development of containment technology. The major objective of the research is to

随着对地下水供应的需求日益增加，迫切需要制定战略，保护宝贵的地下水资源不受污染。通过使用胶态二氧化硅（CS）基化学灌浆进行环境控制正成为地下水保护的重要步骤。CS凝胶还用于岩土工程应用和石油二次开采期间的强化采油操作。虽然在这一重要领域已经做出了一些努力，但还没有任何协调一致的努力来理解与这些胶凝溶液通过多孔介质的流动和运输相关的过程。因此，迫切需要一个研究计划，通过实验和数值研究来发展我们对化学灌浆过程的理解，以促进我们对安全壳技术发展的认识。研究的主要目的是
