| It comes to be an important point to judge precisely the effects of excavation on adjacent ground and structures. It is incorrect to evaluate the ground settlement by excavation without considering the adjacent structure. In this study, laboratory scale tests were carried out by varying the position of structure under the condition of different system stiffness and wall friction to evaluate the behavior of adjacent structures and ground by excavation. When the distance between the structures and the wall was less than 0.3 times of the excavation depth, the ground settlement increased by 181%. No additional effect was observed when the distance was more than 1.0H. As the embedded depth was deeper, the influence zone was smaller, and few additional settlements and angular displacement were observed when the embedded depth was more than 0.75H. |
