摘 要: 在软土路基加固中，采用混凝土桩能更好地利用持力层的承载力，有效提高软土路基的稳定性。通过调整桩长、压桩力等措施，能够使桥台桩基与软土路基之间的过渡段形成协调沉降，消除桥头跳车现象。提出了设计时采用长而稀的布桩原则、适当的桩帽、改进施工工艺等措施，可有效减少挤土效应，保证施工质量。
Abstract: During the strengthening of the soft soil roadbed, the bearing capacity of the bearing layer can be used more sufficiently with the concrete piles and the stability of soft soil roadbed can be improved. By the methods of adjusting the length of piles, pile driving pressure and so on, the transition section between abutment pile foundation and soft soil roadbed can be coordinately settled, and the phenomenon of vehicle dumping can be eliminated. In addition, when designing, using the principles for long and thin pile distribution, appropriate pile caps, improved construction technology, etc. can effectively reduce the soil compaction effect and ensure the construction quality.
