摘要
湿陷性黄土在浸水过程中结构弱化,湿陷变形发展很快,量也很大,强度大幅度降低,在湿陷性黄土地区进行工程建设时,必须进行地基处理。通过分析黄土湿陷性机理及其影响因素,提出了将增湿高能级强夯法应用于湿陷性黄土地基处理的方法,经试验检测,其加固效果较好,消除了黄土湿陷性的同时,还提高了黄土的强度。
The structure of collapsible loess weakens in the process of soaking, thus the collapse deformation develops rapidly, the collapsibility deformation is also large and the strength significantly decreases. When the construction is in the collapsible loess areas, the foundation must be processed. By analyzing the collapsible mechanism and influencing factors of the loess, the humidification dynamic compaction method in processing collapsible loess foundation is suggested. By the test for detection, the reinforcement effect is found to be better. The loess collapsibility is eliminated and the strength of loess is improved.
