摘要
以某超大型盾构出洞冻结法施工中的地下连续墙监测为例,介绍了盾构出洞过程中地下连续墙所受冻胀压力、顶端水平位移和相对弯曲变形的监测方法。通过现场实测数据分析,证明用实时监测方法调整冻结和洞门凿除施工可保证盾构安全顺利出洞。
Taking underground continuous wall monitoring in an outer well construction of large diameter shield by artificial ground freezing method, the monitoring methods of the frost-heave pressure on underground continuous wall, the displacement at the top and the relative distortion of underground continuous wall in the outer well construction by freezing method are introduced. It is shown that regulating the work of freezing and digging in tunnel portal by field monitoring guarantee the security of outer well construction.
