摘要
结合具体工程实例,分析了液氮冻结原理,探讨了液氮冻结法在盾构进洞工程中的应用,介绍了具体的冻结方案和冻结效果,实践证明该方案是安全可靠的,在其他类似地下工程中有推广应用价值。
Combining with the concrete engineering example, the freezing principle of liquid nitrogen was analyzed, the application of liquid nitrogen freezing method in shield entry engineering was discussed, and the concrete freezing schemes and freezing effects were introduced. The practice shows that this scheme is safe and credible, which has extension and application value in other similar underground engineering.
