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

Flowable fill is control low strength material(CLSM) qWtvo';3  
5>"$95D  
This material is  backfiledl behind retaining wall. Modelled by PLAXIS: V;~W,o!

Undrained condition, M-C model. hFZ7

How about the Poisson's ratio(effective value) and Young's Modulus? (m=-oQ&Ro  
(just the general value) S!2M?}LU  
: UD<1fh  
Thanks,

Miu=0.49,undrained material 1N1MD@C?P  
E=1.0Mpa~2.5Mpa,depends on the water content ,void ratio, and depth of the backfill.

Thanks, R.!'&<Svq  
If I need input the effective poisson's ratio for drained condition, ;a XcGa  
what's value for this(u')?

Plaxis recommend miu=0.25 for effective state. dMQtW3stY  
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? g03I<<|@
