摘要

人工冻结法因其环保、安全可靠的特点,在地下工程建设中被广泛应用。本研究以福州地铁某区间联络通道为工程依托,采用现场实测以及数值模拟等研究方法对冻结-开挖全过程冻结帷幕温度场与位移场耦合的演化规律进行研究。结果表明:为减小大体积冻结带来强冻胀影响,选用双侧错开冻结方式进行冻结,冻结完成时左、右侧地表位移分别为64.51 mm、76.72 mm;在联络通道开挖过程中,冻结帷幕的最大位移收敛为1.52 mm,最大位移收敛速率为0.082 mm/d,均远小于控制值;在不同支护时机下,冻结帷幕的变形与位移变化均随支护时机的延长而增大,但各监测点的平均竖向位移变化均小于0.03 mm/d;开挖步距从1.5 m增大到2.5 m,冻结帷幕的底部隆起和顶部沉降分别增大了1.16倍、5.56倍;开挖步距在1.5 m~2.0 m时产生的竖向位移变化均大于开挖步距在2.0 m~2.5 m时的竖向位移变化。研究成果可为今后超长地铁联络通道冻结-开挖工程提供参考。

Abstract

The artificial ground freezing method is widely used in underground engineering due to its environmental friendliness, safety, and reliability. This study is conducted based on the connection passage of a section of the Fuzhou metro. Field measurement data and numerical simulation are used to investigate the coupled evolution of temperature and displacement fields of the frozen curtain during the freezing-excavation process. The study results indicate that: A staggered freezing method on both sides was chosen to reduce the strong frost heave impact caused by large-volume freezing. Upon completion of freezing, the surface displacements on the left and right sides were 64.51 mm and 76.72 mm, respectively. Upon completion of the freezing process, the surface displacements on the left and right sides were 64.12 mm and 73.84 mm, respectively. During the excavation, the maximum convergence displacement of the frozen curtain was 1.52 mm, and the maximum displacement convergence rate was 0.082 mm/d, both well below control values. Under varying support timing conditions, deformation and displacement of the frozen curtain increased with extended support timing. The average vertical displacement change at each monitoring point is less than 0.03 mm/d. Increasing the excavation step length from 1.5 m to 2.5 m resulted in the frozen curtain's bottom heave and top settlement increasing by 1.16 times and 5.56 times, respectively. Vertical displacement changes were greater when the excavation step length was between 1.5 m and 2.0 m compared to when it was between 2.0 m and 2.5 m. These findings can be a reference for future freezing-excavation projects of ultra-long subway connecting passages.

Key words： artificial ground freezing method; displacement field; freeze-excavation; frozen curtain; super-long connection passage
