In this paper, the development of a TSC—1 data processing system for triaxial testing is presented. The TSC—1 data processing System is an automatized instrument including automatized measuring and processing of test data, and it can be used to complete the triaxial shearing apparatus. All its functions are realized by a computer under the order of special mathematical models. When the TSC—1 instrument is combined with triaxial apparatus, the relationship between dispersion of pore pressure and time can be obtained during drainage consolidation of samples, and the changes of deviatoric stress and pore pressure with strains can also be obtained, separately, during the shearing of samples. The TSC—1 system is applicable to the triaxial compressure test under strain or stress control conditions. Preliminary tests on this instrument show that the TSC1system has the following advantages: reasonable in design, stable in performance, easy to operate and reliable in test results. With this instrument, the labour intensity and repeated calculations can be reduced. It is, therefore, a reasonable and helpful automatized instrument, and it has been put into production in small batches.
