膨胀性土作为区域性特殊土,具有浸水膨胀、失水收缩的工程变形特点,导致其力学性能很不稳定.从改善膨胀性土力学性能,满足工程承载力和变形要求出发,根据某危桥维修加固工程,研究总结了改善膨胀性土力学性能的处理机理.工后检测结果表明,无砂砼压密注浆小桩对膨胀性土的改性处理,理论上是科学的,实践中是可行的,可为同类加固工程提供一定的参考.
- Abstract:

As a regional special soil, expansive soil has the characteristics of engineering deformation of water immersion expansion and water loss contraction, resulting in unstable mechanical properties. Starting from improving the mechanical properties of expansive soil and meeting the requirements of bearing capacity and deformation of the project, the treatment mechanism for improving the mechanical properties of expansive soil is studied and summarized according to the maintenance and reinforcement project of a dangerous bridge. The post-construction test results show that the modification treatment of expansive soil by compacted grouting piles without sand concrete is scientific in theory and feasible in practice, which can provide a certain reference for similar reinforcement projects.
