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

Flowable fill is control low strength material(CLSM) V;-YM W  
=ADdfuKN  
This material is  backfiledl behind retaining wall. Modelled by PLAXIS: juc;]CHt'  
*yxn*B_xZ  
Undrained condition, M-C model. %;{Ro)03  
C0@[4a$8f  
How about the Poisson's ratio(effective value) and Young's Modulus? (77EZ07%  
(just the general value) &;O)Dw  
NN;'QiE  
Thanks,

Miu=0.49,undrained material ADQ#qA,/  
E=1.0Mpa~2.5Mpa,depends on the water content ,void ratio, and depth of the backfill.

Thanks, 17nONhh  
If I need input the effective poisson's ratio for drained condition, i!jR>+  
what's value for this(u')?

Plaxis recommend miu=0.25 for effective state. C/w!Y)nB=  
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? $]G_^ji)K
