草炭土路基处理方法研究

Analysis on treatment of peat soil foundation

为选择合适的草炭土路基处理方法,通过理论分析,对工程实例中遇到的草炭土路基,拟定塑料排水板法和砂桩挤密法处理措施,并对两种方法的处理效果进行了对比。研究结果表明砂桩挤密法无论是从提高固结度,加快草炭土路基固结,还是减小工后沉降,保证路基运营稳定方面都要优于塑料排水板法。砂桩挤密法更适用于草炭土路基处理。

In order to select an appropriate foundation treatment of peat soil,the authors make a theoretical analysis of peat soil foundation. Two main methods-prefabricated drains and sand pile are compared in their management effects. The comparison reveals that the sand pile method is precede in increasing consolidation degree, accelerating consolidation velocity of the peat soil,decreasing subsidence and guaranteeing the roadbed stabilization. Sand pile is more suitable in peat soil formation disposal.
