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

Flowable fill is control low strength material(CLSM) ws!~MSIy  
QNU~G3  
This material is  backfiledl behind retaining wall. Modelled by PLAXIS: !^su=c  
\-;f<%+  
Undrained condition, M-C model. z_ycH%p  
B^P&+,\[}  
How about the Poisson's ratio(effective value) and Young's Modulus? J({D~
 
(just the general value) b-  t  
EXVZ?NG  
Thanks,

Miu=0.49,undrained material I]e+5 E0  
E=1.0Mpa~2.5Mpa,depends on the water content ,void ratio, and depth of the backfill.

Thanks, Nv36#^Z  
If I need input the effective poisson's ratio for drained condition, .aY$-Y<  
what's value for this(u')?

Plaxis recommend miu=0.25 for effective state. #Iz)Mu  
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? _(h=@cv

thanks.....
