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

Flowable fill is control low strength material(CLSM) l\l\T<wa,  
*GsrG*OM*D  
This material is  backfiledl behind retaining wall. Modelled by PLAXIS: !/0XoIf"  
-B\`O*Q  
Undrained condition, M-C model. ,nO:Pxn|  
:z=/z!5:j  
How about the Poisson's ratio(effective value) and Young's Modulus? =Ewa}$-  
(just the general value) 4i'2~w{/  
Zxw>|eKI>D  
Thanks,

Miu=0.49,undrained material yc,Qz.+g  
E=1.0Mpa~2.5Mpa,depends on the water content ,void ratio, and depth of the backfill.

Thanks, ;D_6u(IC4:  
If I need input the effective poisson's ratio for drained condition, S\<]|tM:x  
what's value for this(u')?

Plaxis recommend miu=0.25 for effective state. g<~[k?~J  
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? ZMJ\C|S:
