N2  - Control  ground  movement  around  deep  excavations  is  important  problem  in crowded city to decrease its influence to adjacent buildings. Thus, a study of characteristics of ground movement in deep excavation and its effect on adjacent structures are important to  predict  degree  of  magnitude  and  pattern  ground  movement  as  well  as  damages  of adjacent buildings near excavations.Measurement  data  of  10  braced  excavations  in  urban  area  of  Ho  Chi  Minh  City using  concrete  diaphragm  walwere  assessed  and  generalized.  These  excavations  for  high rise building basements were made mainly in medium dense sands at depth between 7.8m and 25.5m. Maximum normalized lateral wall movement (({uF064}Hmax/H) was 0.88%. In braced mode, almost ({uF064}Hmax/H) was equal or lower0.2%, it is similar with observes of Clough and O{u2019}Rourke (1990). Besides, normalized lateral wall movement shows a trend of an increase in wall movement with decrease in system stiffness as defined by Clough et al (1989).An  increase  modulus  value  of  sand layers by about 3 times original value ( E{u2019}= 3000-6000N for back analysis instead of E{u2019} = 1000-2000N  usually)  was  demanded  for  a better predict. And workmanship factor in strut installation is important to effect to lateral wall movements.The influence zone of braced excavations using diaphragm wall in sand to adjacent buildings can reach to 2H form diaphragm walls ( H depth of excavation) and limit in 1H if drawdown can be control
