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

Flowable fill is control low strength material(CLSM) 3?}SXmA'@  
_88~uYG  
This material is  backfiledl behind retaining wall. Modelled by PLAXIS: !9N%=6\

How about the Poisson's ratio(effective value) and Young's Modulus? jf2E{48P  
(just the general value) 4i19HD_

Thanks,

Miu=0.49,undrained material 3A9|{Vaz+6  
E=1.0Mpa~2.5Mpa,depends on the water content ,void ratio, and depth of the backfill.

Thanks, {xr

If I need input the effective poisson's ratio for drained condition, E5dXu5+ye  
what's value for this(u')?

Plaxis recommend miu=0.25 for effective state. 0v_8YsZ!`$  
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? qEAF!iB]L
