%X In order to study the long term mechanical properties,the double-linkage triaxial testing machine for hydro-mechanical coupling in soft rock is developed. This machine is particularly applicable to study the rheological characteristics of soft rock and hard soil under various stress conditions. Using the technology of servo-controlled,ball screw and hydraulic pressure,this machine can automatically stabilize voltage and record stress-strain variation curve and temperature duration curve. In addition to the function of ordinary triaxial device,because of the unique design form of this machine,it not only can implement the mechanical tests simultaneously of two samples with same axial pressure,different confining pressures and same water pressure but also execute confining pressure control,pore water pressure control and its survey,etc.. The service condition shows that it is a convenient machine with complete functions,simple structure,good stability and high precision.
