预应力管桩在某高铁客运站深厚软基处理中的应用

Application of PHC pile in deep soft ground treatment for high speed railway station

针对西南某高速铁路客运站深厚软基高填方工程,在现场成桩试验基础上,研究了预应力管桩在环滇池地区深厚淤泥质土中的适用性,对施工完毕后的填方过程进行了沉降监测。监测表明,沉降稳定,无病害发生,整治效果良好,为以后同类工程提供了一定的参考经验。

For a southwest high speed railway station deep soft base high fill project. The adaptation of PHC pile used in the deep mucky soil around the Dianchi is researched on the base of the pile site test. After the construction,the observation of embankment deformation was performed. Results of monitoring indicated that the ground settlement was stable and there was no disease happened. In general,the ground treatment has get a good result. It offers certain reference experience for the same kind of engineering.
