Study on critical length-diameter ratio of cement-soil pile composite subgrade under rigid foundation TAO Chuan-qian1,a, XU Xue-yan2,b, XIE Heng-yan1,c, ZHENG Xin1,d 1College of Engineering, Heilongjiang Bayi Agricultural University, Daqing 163319, China 2School of Civil Engineering, Harbin University of Technology, Harbin 150090, China agcxytcq@126.com, bxxyan@hit.edu.cn, cxiehy555@163.com, dzx07@yahoo.cn Keywords: cement-soil pile; composite foundation; critical length-diameter ratio; replacement ratio Abstract: For cement-soil pile composite subgrade under rigid foundation, a three-dimensional nonlinear finite element analysis is performed to analyse critical length-diameter ratio based on deformation, which is first introduced, according to replacement ratio, pile-soil modulus ratio and the modulus ratio of substratum and reinforced area.
Especially, an extensively concerned problem in engineering is how to determine effective length of cement-soil pile.

Among the various applications of MR fluids, MR dampers have gained considerable attention in vibration control of civil and mechanical structures as well as bio-mechatronic applications such as prosthetic limbs.
This approximation, which is widely used in designing and modeling of MR dampers, is satisfactory for many engineering purposes.
