(HP-67) Shear-Wave Measurement (soil deformation) - SlideRule - 07-27-2019 03:38 PM An extract from Shear Wave Measurements of Deformation Properties of Soil, Colin Peter Abbiss, Imperial College of Science and Technology, August 1983 (213 pgs.) The arrival time T of the leading edge of the s wave pulse was plotted against distance x … These time distance curves were fitted by the formula … This was carried out by a programmable calculator, the HP 67 see program in Appendix 3, or by computer … Another calculator program has been written which finds the depth Z corresponding to the distance x and also enables one to find the maximum depth Z for the maximum range x of the survey … The fits were carried out by calculator program … The results of fitting the data by calculator are given in Table 2.1C … The data was fitted by the calculator programs and the results are shown in Tables 2.2A … A calculator program reduced the number of possibilities … There are six possible solutions listed in Table 3.2A with 4 in six possible ranges of angle. The correct solution is identified with the calculator program … A simple calculator program has been written so that the calculation may be undertaken in the field … APPENDIX 3 - CALCULATOR PROGRAMS… Thorough & complete.
