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

Flowable fill is control low strength material(CLSM) 7e<Q{aB  
jb2:O,+!  
This material is  backfiledl behind retaining wall. Modelled by PLAXIS: [s2V-'2  
gsp7N  
Undrained condition, M-C model. q':wSu u  
@7=D]yu  
How about the Poisson's ratio(effective value) and Young's Modulus? `[\phv  
(just the general value) &3f.78a  
|7$h@KF=S  
Thanks,

Miu=0.49,undrained material Z5L1^  
E=1.0Mpa~2.5Mpa,depends on the water content ,void ratio, and depth of the backfill.

Thanks, d %W}w.  
If I need input the effective poisson's ratio for drained condition, -3tBN*0+  
what's value for this(u')?

Plaxis recommend miu=0.25 for effective state. chmJ|  
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? E(!6n= qR

thanks.....
