| Abstract: | Foundation reinforcement by high pressure jet grouting piles cannot reach an ideal sealing when used in quicksand stratum due to its own deficiencies.Taking the project of Binjiangdadao to Zhujiang East section of Metro 10 in Nanjing as an example,this paper shows the advantages of freezing reinforcement in quicksand stratum,and demonstrated the feasibility of artificial freezing reinforcement method in the construction of shield entering cave. |
| Keywords: | underground construction shields vertical local freezing conjunction reinforcement freezing reinforcement analysis |
