高填方湿陷性黄土路堤填筑技术

Filling Technology of High Filled Collapsible Loess Embankment

从施工工艺的全过程分析及采取的有效控制手段,证明论文所述高填方湿陷性黄土路堤的填筑施工方案可行。具体操作办法是:通过对填料的试验测定,采取重锤夯实、2层三七灰土进行基地的处理。同时,填筑过程中和沉降期内加强沉降观测,以数据严控和指导施工,最终有效地避免了湿陷性黄土路堤填筑施工中经常出现的病害。

Based on the analysis of the whole process of construction technology,the effective control measures are adopted to prove the feasibility of the construction scheme of the high filled collapsible loess embankment. The specific operation method is：through the test of the filler,take the heavy tamping,two layers of 37 lime soil base treatment. At the same time,the settlement observation in the filling process and the settlement period,the data strictly control and guide the construction,and ultimately effectively avoid the collapsible loess embankment filling construction often appear in the disease.
