In applying deformation control, it is vitally important to accurately determine the soil pressure being applied to the retaining structure, which is also closely dependent on the deformation of the adjacent soil.

• 目前基坑开挖设计已逐步由强度控制转变为变形控制,在变形控制当中如何准确地确定作用在支护结构上的土压力是至关重要的,而作用在支护结构上的土压力又与支护结构相邻土体的变形紧密相关。
