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

Flowable fill is control low strength material(CLSM) V7gL*,3>=  
eUR+j?5I  
This material is  backfiledl behind retaining wall. Modelled by PLAXIS: OQ<;w  
;KmrBNF  
Undrained condition, M-C model. })(robBkA  
i7YUyU  
How about the Poisson's ratio(effective value) and Young's Modulus? !-%%94Q  
(just the general value) t*Z5{  
f qWme:x  
Thanks,

Miu=0.49,undrained material ?GLCd7TP  
E=1.0Mpa~2.5Mpa,depends on the water content ,void ratio, and depth of the backfill.

Thanks, ~Ij/vyB_  
If I need input the effective poisson's ratio for drained condition, B^R44j]3"  
what's value for this(u')?

Plaxis recommend miu=0.25 for effective state. hV) `e"r\s  
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?  fWs*u[S
