有朋友问到EAEI问题,有外文资料如下,可供参考,高手可将它翻译出来贴在本版块,以供后人学习---
Q: How do we select the values for EA, EI and w when modelling a pile group as plain strain?
A: To obtain the axial stiffnes EA and flexural rigidity EI you have to divide them by the spacing between the piles.
The weight of the beam has to be modified also because of the soil between the piles.
In addition to these factors, Rinter, the interaction factor between the soil and the beam has to be changed also, it has to be higher. There is less interaction between the beam and the ground because there is soil between the piles.
