Design of Roadbed Treatment behind the Abutment of Bridge No.2 on the Min'an Road
In order to discuss the subgrade treatment method behind the No.2 abutment of Min'an Road in Jiangxin Island,the numeri-cal simulation was carried out with Lizheng software to calculate the settlement of cement mixing pile and bubble mixed light soil treat-ment methods,and comprehensive comparison was made based on the factors such as cost,surrounding pipelines,project duration,etc.Analysis shows that both treatment methods can meet the requirements of post construction settlement.Bubble mixed light soil has obvi-ous advantages in terms of roadbed integrity,engineering cost,project duration,etc.Finally,bubble mixed light soil was adopted for the treatment of the post construction roadbed of Min'an Road No.2 abutment.
