水泥土搅拌桩在堤坡稳定中的应用

Application of cement-soil mixing pile in stability of embankment slope

水泥土搅拌桩是将软土与固化剂通过特定的机械进行强制搅拌,把软土变成具有一定整体性和强度的水泥加固土体。其不仅能使软土地基压缩模量增大,还在软土堤坡中起到一定抗滑作用。以实际工程为例,进行不同工况下堤坡稳定计算处理,并对水泥土搅拌桩桩身位置进行探讨分析,以对实际工程具有参考意义。

Cement soil mixing pile is used to make the soft soil and the hardener to be forcedly stirred by a specific machine,and to turn the soft soil into cement reinforced soil with certain integrity and strength.It can not only increase the compression modulus of the soft soil foundation,but also play a certain role of anti-sliding in the soft soil embank slope.In this paper,a practical project is taken as an example to calculate the stability of the embankment slope under different working conditions,and the position of the pile body of the cement soil mixing pile is discussed and analyzed,which has a certain reference significance for the practical project.
