ZHANG Yong1,2,ZHAO Yun-yun2(1.School of Civil & Environment Engineering,University of Science and Technology Beijing,Beijing 100083,China;2.College of Resources,Hebei University of Engineering,Handan 056038,China)  
Because foundation pit dewatering causes the readjustment of stresses in soil,it brings uneven settlements and architectural damage of the building around foundation pit;accordingly,real time prediction of land subsidence caused by foundation pit dewatering has the realistic meaning;by using the theory of unsteady well flow and basic theory of soil mechanics,the real time prediction method of land subsidence has been introduced;the rationalities of different parameters in formula have been analyzed via case study;and it has certain meaning to forecast the land subsidence around foundation pit caused by foundation pit dewatering.
