土压力、孔隙水压力、地下水位、地面变形及深层土体移动的变化都跟掘进机与测试断面之间的距离有直接关系。
Change of earth pressure, pore water pressure, underground water level, surface deformation, and sub-surface movement all have direct relationship with distance between shield and testing section.
土压平衡盾构施工通常会对周围土体产生挤压作用,导致地面隆起和深层土体向远离隧道方向移动。
Earth pressure balance (EPB) shield construction often has soil-compacting effects on its surrounding soil. It results in the surface upheaval and moving away of deep soil from the tunnels.
