| Abstract: | Foundation excavation of a construction has a large area excavation,large differences within the soil layer,complex geological conditions,the surroundings being adjacent to buildings,urban roads,ramp slopes,and other different environments.According to the conditions of site,foundation excavation support is divided into seven representative profile to joint support,the support structure is both realistic and economically rational.It is analyzed the construction difficulties such as doing an excavation facing the flow of mud pile,collapse between piles,long side effects,hillside reinforcement and the existing shelter etc;and the corresponding measures are worked out.By carring out safety monitoring of foundation excavation construction,using informational design and constructional technology,the safety of foundation excavation and the surrounding environment is ensured. |
