COMPUTER AIDED DATA ACQUISITION AND ANALYSIS FOR THE CONSOLIDATION TEST

The standard one dimensional consolidation test of soil is carried out over a period of several days or even weeks. The use of electrical transducers, x-y plotters and chart recorders has removed the need for constant surveillance by laboratory staff. However, there is still a considerable amount of data reduction and interpretation required which is tedious and often leads to errors. Small computers are now available which can be used to both take the readings and analyse them. The paper describes how a Hewlett-Packard HP85 computer with an IEEE 488 interface together with a digital multimeter and displacement transducer is used to take and analyse readings. The software to do this is contained in two programs. The test is set up and the readings taken under the control of program conlab. Once the testing is complete the results are analysed by program CONCAL. Extensive use is made of the graphics capability of the computer. Typical results as produced by the equipment for kaolin are presented in the paper. (Author/TRRL)
