摘要
为了从理论上分析水泥混凝土路面板底脱空注浆加固的压力控制及布孔方式,以劈裂注浆压力及扩散半径的理论公式为基础,假设浆液在土体裂缝中的流动符合达西定律,劈裂注浆形成的裂缝宽度为均匀裂缝宽度,推导出水泥混凝土路面板脱空注浆时两孔、三孔、四孔和五孔注浆布置方案在注浆加固的布孔方式下注浆压力设计计算方法。研究结果表明:理论计算结果与实测结果较接近,证明了计算方法的合理性,理论分析的结果可为工程应用提供可靠依据。
In order to analyze the design of holes arrangement and its grouting pressure of void treatment beneath cement concrete pavement,based on the assumption that the grouting flow in soil crack is in accordance with H.Darcy law and the last formative crack breadth is even crack breadth,2,3,4 and 5 designs of holes arrangement and grouting pressure for void road were given.These conclusions are proved true by making use of numerical analyses method.These theories are useful for engineering application.
