FLAC^(3D)在采空区注浆加固中的应用

The Application of FLAC^(3D) in Goaf Grouting Reinforcement

在采空区上方兴建建筑物前必须先进行地基稳定性评价,进而根据实际情况采取相应的处理措施。在众多不同的处理方案中,经实践证明,注浆加固处理是最直接、最有效的处理措施。结合采空区注浆加固机理及其涉及到的问题分析了FLAC3D在此领域应用的优越性,并应用FLAC3D软件对采空区注浆加固问题进行了模拟分析。

The evaluation for foundation stability should be done before the construction of buildings above the goaf,then appropriate measures should be taken according to the actual situation. In many different treatment programs,grouting reinforcement is the most direct and effective measure. The paper,combined with the mechanisms and problems involved in grouting reinforcement,analyzes the advantages of FLAC3D in this field,and makes simulation analysis about goaf grouting problem by FLAC3D.
