摘要
高压旋喷桩地基加固法自身存在某些缺陷,无法在流砂地层中达到理想的封闭效果。通过南京地铁十号线滨江大道站—珠江东站区间盾构接收工程实例,阐述了冷冻加固在流砂地层中具有的优势,论证了人工冷冻加固法在盾构进洞上的可用性。
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.
