Study On Foundation Reinforcement Of Existing Building Adjacent Slope

With the steady development of the national economy and the building land is increasingly tense,resulting in a large number of buildings on the slope.Both the buildings and the slope are the unity of interaction,the building had adversed effect on the deformation and stability of the slope soil.However,the slope of the slope can causes uneven settlement of the foundation and even cracks or tilts of existing buildings.Based on a certain district of zhangjiakou in a nearby the slope of the masonry structure settlement needs reinforcement as the background,using the finite element software ABAQUS to study the deformation of slope and foundation and the settlement of the reinforced building.The main research content includes:(1)Based on the domestic and foreign research results of the region,according to the practical engineering geological conditions.The design and calculation of slope support and foundation reinforcement are designed according to the standard design theory,and the slope support scheme and foundation reinforcement plan are determined.(2)The finite element software ABAQUS is adopted to model the project and to analyze the front and rear side slopes and the changes of the existing building,which evaluates the safety and reinforcement effect of the reinforcing scheme of this project.(3)In this paper,the pile diameter and pile length of the pile length of the pile length are changed,and the influence of different parameters is analyzed,and the effect of the reinforcement and slope reinforcement of the adjacent slope is also affected.The results show that the control effect on the settlement of existing buildings in the adjacent slope is obvious by the use of double row pile support and the building foundation.The pile length of double row piles,the height of connecting beam and the length of pile length and the diameter of the pile have influence on the settlement of foundation settlement.Considering the economic and security factors,choosingreasonable reinforcement parameters can receive good reinforcement effect.
