%X In order to explore the ways of applying bacterial foraging optimization(BFO) algorithm  to geotechnical engineering, we adopted BFO algorithm to invert objective function of rheological model based on data collected from rock mass rheological test of rigid bearing plate. The tunnel anchorage project on the north shore of the proposed Jijiang Yangtze River Bridge was taken as research background. Furthermore we compared the inversion surface displacement curve with the measured displacement curve and found that the curves were generally consistent, indicating that the compressive rheological properties of rock mass can be reflected by generalized Kelvin model and parameters inverted by BFO algorithm. It is effective to invert compressive rheological parameters using BFO algorithm. Meanwhile, it has high computation speed, high efficiency and precision, hence is an effective approach to invert compressive rheological parameters.
