多级边坡公路施工中软土路基高强度防沉陷处理

High Strength Auti-subsidence Method of Soft Soil Roadbed in Multi-stage Slope Highway Construction

提出基于水泥搅拌桩的软土路基高强度防沉陷处理方法。首先对软土路基特性以及软土路基强度与稳定性、软土路基压缩及不均匀沉陷问题进行分析,结合对软土路基的分析利用水泥搅拌桩法对多级边坡公路施工中软土路基高强度防沉陷进行处理,完成对多级边坡公路施工中软土路基高强度防沉陷处理方法研究。实验结果表明,该方法能有效地解决软土路基不均匀沉陷,提高公路的施工质量,具有广泛应用价值。

This paper proposes a processing method of soft soil subgrade subsidence prevention high strength cement mixing pile based on.First,the characteristics of soft soil subgrade,and the strength and stability of soft soil subgrade in soft soil roadbed compression and uneven subsidence problems were analyzed,combined with the analysis of soft soil subgrade by cement mixing pile method of multistage slope highway construction of soft soil road high strength anti subsidence treatment,after treatment of anti paired multi-stage slope of highway construction subsidence soft soil road high strength.The experimental results show that this method can effectively solve the uneven settlement of soft roadbed and improve the quality of highway construction,and has wide application value.
