displacement of ground surface

基本解釋

Furthermore, peripheral displacement convergence and settlement of vault and ground surface are monitored on-site.
現(xiàn)場(chǎng)對(duì)隧道周邊位移收歛值、拱頂下沉值和地表下沉值進(jìn)行監(jiān)測(cè)。
However, the displacement and deformation of surface ground by underground mining have destroyed initial equilibrium between the building and the ground.
但是由於地下開採引起地表産生的移動(dòng)和變形，破壞了建築物與地基之間的初始平衡狀態(tài)。
Together with the outcome existed, deduces the simplify equation of the ground surface displacement and deformation induced by the excavation in the free field;
