【Abstract】 Due to the large uneven settlement of collapsible bearing layer in foundation ground,the structure wall cracks are found in the 5_story building,which became dangerous.The optimization of engineering plan is concerned in result of adopting static mini_pile reinforcement.A favorable effect is gained.In this paper,the principle of static mini_pile underpinning is described and the problems which should be noticed in the process of design and construction are discussed,and some useful conclusions are also put forward.更多还原
