主要对珠江三角洲高速公路建设中常用的排水固结法、排水固结法＋换填轻质填料、搅拌桩复合地基、CFG桩复合地基、管桩地基等5种软基加固处理方法,开展了基于专家调查的高速公路软土地基加固处理方法可靠性分析与研究。通过对来自高速公路管理、设计、施工、研究单位的67位具有丰富的软土地基加固处理工程经验的专家开展咨询和调查分析,得出了不同软土深度情况下各种软基加固方法的可靠性程度评价结果。研究显示,珠江三角洲软土路基加固处理方法的可靠性从高往低的排列顺序依次为管桩地基、CFG桩复合地基、排水固结法＋换填轻质填料、排水固结法、搅拌桩复合地基。当软土深度超过20m时,一般宜采用管桩进行地基加固处理。

The paper researches reliability of 5 soft foundation reinforcement methods used in highway construction on the basis of experts survey in the Pearl River Delta. Through consulting and survey analysis of 67 experts with abundant soft soil improvement experiences from the highway management, design, construction, research enterprises, the reliability evaluation has been drawn for vari- ous kinds of soft ground treatment methods in different depth. The results show that, in the Pearl River Delta, the reliability of treat- ment methods lines from high to low as pipe pile foundation, CFG pile composite foundation, drainage consolidation method with light material replacement, drainage consolidation method, mixed pile composite foundation. When soft soil depth reaches more than 20 m, pipe pile foundation method will be generally adopted for soft soil foundation treatment.
