摘　　要：部属 95 G5 1 - B科研项目对广深准高速铁路运营状态追踪测试表明 ,部分桥头软土路基存在严重下沉急待处理 .本文阐明了既有线上水泥旋喷法的适用性 ,并通过对珠江三角洲软土的加固材料、配比方案、外加剂和有机质含量等分项对比试验分析提出了相关结论 。The running state of paramilitary high speed railway from Guangzhou to Shenzhen is traced and tested.This scientific project is subordinate to the minstry.The research shows that certain ends of bridges soft soil roadbed is subsiding seriously and needs to be dealt with urgently.The paper expounds the suitability of chemical churning pile for existing line and puts forward relevant conclusions obtained from paxtition items of contrast experimental analysis which involved in consolidating material,mixing scheme,chemical additive and organic matter content of Zhujiang River Delta soft soil.The conclusions offer the experiment basis for choosing the design parameters and judging the consolidatiny effects.
