Why should the deep foundation pit support axial force monitoring? Or what is the monitoring of the supporting axial force in order to know the state of the foundation pit? Like this, a few words summed upColumn settlement monitoringPost settlement monitoring, foundation pit excavation and precipitation affected during the construction process, the pile may produce uneven settlement, post too much uneven settlement will cause the entire support system instability, therefore need to monitor post settlement.I was in order to do the monitoring program, the trouble to know back, thank you!!!
There is a problem with our numerical axial force meter measured are small, usually the first force only after the pre 30%~70% value, sometimes even very small, and they force to support unit said, as a result of retaining wall (pile) large deformation,
When the retaining wall to the foundation pit displacement occurs, the axial force of steel support will gradually become largerI do not know how much of the total value of the pre reinforcement can be achieved when the first Afterburner
Generally, the supporting structure of continuous wall (pile) and steel support is used. We are using the axial force meter (anti force meter) test, relatively stable his surname is good, can instantly reflect the conditions. They also used the steel stress meter, surface gage, the effect is not how good, especially the strain gauge could not reflect the working condition, and easily broken (numerical measure out), do not know is not associated with the installation process?
