摘要
结合工程实例,探讨了某些不均匀土层条件下,采用局部冻结加固的联络通道施工工艺及施工要点,提出了采用测温孔、泄压孔、探孔等多种方式进行地层加固效果评判,对类似地层施工具有参考意义。
Combined with engineering examples,the paper discussed the construction technology and key points of subway connecting passage strengthened by local soil freezing under some uneven soil conditions.It is proposed to use temperature measurement hole,pressure relief hole and probe hole to evaluate the effect of formation reinforcement.It has reference significance for similar stratum construction.
