[求助]Help:How to decide the properties for Flowable fill? [复制链接]

Flowable fill is control low strength material(CLSM) :>f )g  
@,7GaK\  
This material is  backfiledl behind retaining wall. Modelled by PLAXIS: %RRNJf}z  
k)=s>&hl  
Undrained condition, M-C model. hRCJv#]HC  
3ym',q  
How about the Poisson's ratio(effective value) and Young's Modulus? H=
v
UYz  
(just the general value) 9-a0:bP  
YfKdR"i+.  
Thanks,

Miu=0.49,undrained material D.u{~  
E=1.0Mpa~2.5Mpa,depends on the water content ,void ratio, and depth of the backfill.

Thanks, Z0", !6nS  
If I need input the effective poisson's ratio for drained condition, i3mcx)d@H  
what's value for this(u')?

Plaxis recommend miu=0.25 for effective state. Y)2,PES=  
PS: HS model, you can see the default miu of advanced settings.

may i know, if the poisson ratio is high, the soil displacement will be smaller or larger? xOmi\VbM

thanks.....
