Variety is spice of new generic software

FRENCH INSTRUMENTATION manufacturer and supplier Jean Lutz has developed a generic software package that can be used for a variety of geotechnical applications.

The software, designed to work with the firm's monitoring equipment, features programs for rotary drilling work including ground anchoring, micropiling, grouting and vibroflotation.

Each produces summary reports, including graphical printouts of drilling operations. Statistical analysis and interpretation of results based on insitu measurements is also carried out, quantifying ground behaviour in relation to the mechanical stress induced in the ground by the geotechnical work. The two main programs are EXEPF/ECL and EXPVD.

The EXEPF/ECL software first calibrates the drilling parameters of the rotary rig before analysing the drilling processes and interpreting ground conditions. Jean Lutz says that on big contracts, where a large number of rigs are used, the calibration means a quantitative comparison of results from different machines can be done with more confidence.

For grouting work, the EXPVD program collates and analyses the vast amount of data including pressure and flow, to produce a graphical account of grouting operation and an interpretation of the ground conditions. The firm says this enables a check on the suitability of the grouting for the underlying geology. And analysis can also quantify soil improvement by comparing parameters before and after grouting.

Jean Lutz says that because the software uses insitu measurements to analyse ground behaviour during work, the number of control tests needed should be reduced.
