| Abstract: | 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. |
