Application of the Space-Time Effect Theory in the Soft-Soil Foundation Construction

Liu Aihua,Li Hong,Luo Rongwu(School of Resources and Safety Engineering,Central South University,Changsha 410083,China)  
The construction of soft soil deep foundation is not only related to the soil excavation but also associated with the safety and cost of foundation construction.The soft soil,due to its wide spread and great thickness,shallow burial and low strength,will make the foundation construction more difficult.In order to have further research on the variation of stress field and strain field and especially the displacement problem in soft soil with great rheology due to excavation,and to avoid the environment damage and economic loss caused by soft soil foundation construction,the problems were analyzed from the aspect of time-space optimization,and the sectional and time-interval construction in the theory of space time effect could be the effective measures in controlling and reducing the probable maximum displacement of soil.The results of engineering application show that the relationship between the excavation displacement and the space location of construction as well as construction time can be taken into account using this method,which can be effective in the application of the construction of soft soil foundation.
